Development Questions - Assignment Example At the point when meiosis happens, qualities are isolated aimlessly and occasions, for example, traverse can happen, which causes expanded hereditary variety. In bigger populaces, the allelic blends regularly remain stable after some time. Be that as it may, in littler populaces, any sort of variety or creation of one quality over another because of chance can have an enormous change in the genetic stock frequencies. The most valuable approach to consider this idea is as far as the Hardy Weinberg Equation, which is a quadratic recipe that computes the hereditary frequencies of the homozygous predominant, homozygous latent, and heterozygous articulations. The Hardy Weinberg Equation utilizes the letters P and Q so as to addresses the alleles for a populace with homozygous prevailing being p2, homozygous passive being q2, and heterozygous being pq. Ordinarily, in a standard populace and measurably substantial populace, the proportions would be the equivalent. Like expressed above there are different variables, which would then be able to influence the proportion of these allelic frequencies. A portion of the living beings may get by because of matchless quality of the attributes they communicated or the irregularity of gamete development may prompt an unproportional articulation in characteristics. For instance, lets consider a populace which has allelic frequencies of p=0.3 and q=0.7. ... This is on the grounds that a measurable change in allelic frequencies in a littler populace because of chance has a bigger and progressively critical impact in light of the fact that the populace, N, is littler. In this manner, the impact size is bigger. The explanation that it isn't as amazing in populaces with an enormous N esteem is on the grounds that it is imagined that the possibility of one allelic mix being delivered over the other is insignificant, in this manner they offset which shows that there is no genuine coming about possibility in the frequencies of the genetic supply. DNA replication is a procedure, which is progressing at each second in each life form. It is significant so as to guarantee that the structure of the hereditary code stays suitable for multiplication, anyway the code turns out to be progressively disturbed each time that it is recreated. These slip-ups are transformations, which happen in the replication of DNA can make either attractive or unwanted q ualities structure. This is one of the premise in which development is thought to happen. Various sorts of changes effectsly affect development. Substitution transformations are a lot of lower than replacement changes. These are thought to impact impartial qualities, which remain basically comparative after some time. Replacement transformations are thought to occur in qualities that are dynamic and are snappy changing in this is the primary change, which advances the most hereditary variety. Preservation science is the field of science that is coordinated explicitly at understanding and ensuring the biodiversity of the Earth. Understanding the job and relationship of species in their living spaces and environments does this. In particular, Templeton was worried about the human action, which was having an effect on hereditary variety of the nabbed reptiles in the

More generally, Creoles reacted angrily against the crowns preference for peninsulars in administrative positions and i ts declining support of the caste system. After hundreds of years of proven service to Spain, the American-born elites felt that the Bourbons were now treating them like a recently conquered nation. In cities throughout the region, Creole frustrations increasingly found expression in ideas derived from the Enlightenment. Imperial prohibitions proved unable to stop the flow of potentially subversive English, French, and North American works into the colonies of Latin America. Creole participants in conspiracies against Portugal and Spain at the end of the 18th and beginning of the 19th centuries showed familiarity with such European Enlightenment thinkers as Thomas Hobbes, John Locke, Montesquieu, and Jean-Jacques Rousseau. The Enlightenment clearly informed the aims of dissident Creoles and inspired some of the later, great leaders of the independence movements across Latin America.

Ethics of Emergencies - 987 Words

Ethics of Emergencies â€Å"The Ethics of Emergencies† explains Ayn Rand’s radical and unique view of altruism. She believes that there are 4 consequences of altruism, all of which are negative. These, simply put, are lack of self-esteem, lack of respect for others, a pessimistic view of life, and an indifference to ethics. She says that altruism hinders acts of true benevolence, and instead people act out of an obligation to others that has been internalized over time. Rand then argues that one should only volunteer to help strangers in emergency situations, and even then, only when the risk to one’s own life is less than the risk to the stranger’s. Rand advocates action in such emergencies because of the high value of human life. But Rand†¦show more content†¦While I disagree with Rand’s ethics, I think she made an excellent observation concerning human motives in making a â€Å"sacrifice.† The best example is her analysis of why a husband would risk his life to save his wife. Rand says that the true reason the man risks his life for a loved one is because life without that loved one would be too difficult. I agree with her, but in reality, it is a much more emotional and a less cognitive response. The decision to aid the loved one is not made in the way that most rational decisions are constructed. I believe the decision is made in the following way. An individual experiences enjoyable feelings while considering or imagining saving a loved one. While this feeling may fundamentally happen because saving the loved one makes the individual happier than letting the loved one die, I believe the individual does not experience it in this manner. The individual believe the good feeling they experience is their moral conscience. This is a defense mechanism the mind uses to hide the true motive of the behavior and keep the individual ignorant of the selfish reason for â€Å"sacrificing† themselves. While I fo und myself experiencing feelings of frustration and disgust while reading Rand’s essay, I afterwards decided that it was time well spent.

Legalize it Persuasive Essay Example For Students

Legalize it Persuasive Essay No man should have control about something he or she did not create, but that God created. We have minds, and we will choose for ourselves, whether or not we like it. Marijuana has an excellent medical forte. Marijuana also has a very strong historical significance in the United States. It is now used and has been used for centuries for relieving and helping to cure illnesses. There are also many economical benefits for legalizing marijuana. Thus, marijuana has historical significance, medical uses, and economic benefits. Cultivation of marijuana in the United States dates back some four hundred years. Colonialist planted the first American marijuana crop in 1611 near Jamestown. They grew marijuana for its fiber content. King James I ordered the first ordered the cultivation of hemp in the colonies. A majority of colonial sails, bibles, clothing, and maps were made from hemp. Some historians believe George Washington and Thomas Jefferson grew marijuana and promoted a hemp-base society. Marijuana was first considered a mind-altering substance in the 1920s and 30s. During this time the drug was associated with mexican-american immigrants and African American jazz culture. This changed marijuanas image of being an excellent cash crop to being evil. With these accusations and false propaganda about marijuana leading to crime and being deadly, it was made illegal in 1937. The Marijuana Tax Act of 1937 made it illegal after only two one-hour congress meetings. Most of the information presented in these cong ress meetings has been proven false today by our medical society. Today marijuana remains the third most popular recreational drug in the United States. Even though it has been illegal for sixty years. Government figures say 70 million Americans have smoked marijuana. The majority of these people are hard working law-abiding citizens that should not be treated like criminals. Today state police arrest a marijuana smoker every fifty-four seconds. There are harsh penalties inflicted on marijuana smokers, which include incarceration, loss of license even when not driving, loss of child custody, and loss of public housing. As long as marijuana remains illegal, the United States looses money and effort trying to stop the use of plant that grows from the ground. Marijuana has the capability of being manufactured into twenty-five thousand environmentally safe products. This money making potential is being held from American farmers today. Industrial hemp is known as one of natures strongest and most versatile crops. The plant can be used in making various textiles, paper products, paints, clothing, plastics, cosmetics, foodstuffs, insulation, and animal feed. France harvests around ten thousand tons of industrial hemp every year. Currently hemp is grown legally in almost every country in the world except America. Hemp produces a much higher yield per acre than common substitutes. Domestic sales of imported hemp are around 35 million dollars per year. The American Farm Bureau states, Hemp is one of the most promising crops in half a century. American industries such as Adidas, Calvin Klein, and Ralph Lauren added imported hemp to their clothing lines. They have found it to be highly profitable. All of these economical benefits hemp has to offe r and its still considered illegal in the United States. Marijuana makes a large amount of money for our economy legally and illegally. If it were legalized it could make more. Making marijuana illegal looses money for Americas government. The government spends twenty-three thousand dollars a year incarcerating nonviolent marijuana offenders. The prohibition of marijuana looses this countries taxpayers 7.5 billion dollars a year. This large amount of funding should be put forth to target violent ones. Legalizing marijuana will help the issue of scarce jail space in this country and it will help stop clogging our countrys courts. .ud0d9602cd08fb647f6df10715ef6f055 , .ud0d9602cd08fb647f6df10715ef6f055 .postImageUrl , .ud0d9602cd08fb647f6df10715ef6f055 .centered-text-area { min-height: 80px; position: relative; } .ud0d9602cd08fb647f6df10715ef6f055 , .ud0d9602cd08fb647f6df10715ef6f055:hover , .ud0d9602cd08fb647f6df10715ef6f055:visited , .ud0d9602cd08fb647f6df10715ef6f055:active { border:0!important; } .ud0d9602cd08fb647f6df10715ef6f055 .clearfix:after { content: ""; display: table; clear: both; } .ud0d9602cd08fb647f6df10715ef6f055 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ud0d9602cd08fb647f6df10715ef6f055:active , .ud0d9602cd08fb647f6df10715ef6f055:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ud0d9602cd08fb647f6df10715ef6f055 .centered-text-area { width: 100%; position: relative ; } .ud0d9602cd08fb647f6df10715ef6f055 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ud0d9602cd08fb647f6df10715ef6f055 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ud0d9602cd08fb647f6df10715ef6f055 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ud0d9602cd08fb647f6df10715ef6f055:hover .ctaButton { background-color: #34495E!important; } .ud0d9602cd08fb647f6df10715ef6f055 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ud0d9602cd08fb647f6df10715ef6f055 .ud0d9602cd08fb647f6df10715ef6f055-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ud0d9602cd08fb647f6df10715ef6f055:after { content: ""; display: block; clear: both; } READ: The Brethren EssayOn top of all these economical benefits of marijuana there are large medical benefits of marijuana.

Poll results A Primitive Resource: Solar Energy and Its Many Uses Ever since the dawn of time, the sun has been a resource we cannot live or do without, so its not such a shock that man has come up with the idea of solar energy. Solar energy had many uses. Some can be dangerous and some, a very valuable asset to the modern world. Solar energy is energy derived from the sun in a form of ultra-violet rays. Its was first applied to use in 212 B.C., by the Greek genius Archimedes. Solar energy was used to defend the habor of Syracuse against the Roman fleet. Archimedes used a mirror or "burning mirror" as they had called it, to set fire to the ships of the Roman fleets while standing on shore (McDaniels 83). It wasn't until 1615 when Salomon de Caux constructed the first solar device; a solar engine. His device was made of glass lenses, supporting frame, and an airtight metal vessel containing water and air. This produced a small water fountain when the air heated up during operation. This was considered to be more of a toy than a device, but it was the first published account of the use of solar energy since the fall of the Roman Empire (Cheremisinoff 1). Some other use of solar energy after that was the solar roof and the solar oven. The solar roof was thought up by Harold Hay. In a solar roof system, water is contained in a clear plastic bag and it is placed on a black metal roof. Hay got the idea while traveling in India on a technical aid mission for the U.S government. While there, he noticed that many people were living in rusty, sheet metal shacks, which were hot in the day and cold at night. Hay's plan was to remove the insulation from the roof on winter days so that the roof would get hot, and Replacing the insulation at night to allow the shack to be warm through the night. Then in the summer, he would so the reverse of what he did in winter to let the house cool at night and replacing the insulation in the daytime to block out the heat. Then over the years, Hay and a man named John Yellott constructed a 3- by 3.7-m building using water basins as the actual roofing material. During the summer, a slab of foam insulation was rolled back at night, and the water would become cold through the night sky evaporation. Since the water supply sat directly on a metal ceiling, it absorbed the heat from the room and kept the building air-conditioned all day. During the winter, the movable insulation was rolled back in the daytime which allowed for it to collect heat. This generated enough heat into the house through the ceiling at night to keep the room comfortable (McDaniels 179-181). Then there was the solar cooker. Developed by Augustin Mouchot in France and by John Ericsson in the United States in the nineteenth century. They wanted to develop a solar cooker that not only reached high temperatures, but also was to be used as a means of heat storage

The Plant Life Cycle for Kids

The Plant Life Cycle for Kids Plants have a life cycle, just like humans and other animals. The plant life cycle describes the stages the plant goes through from the beginning of its life until the end, when the process starts all over again. Seeds The life cycle of a plant begins with a seed. (Some non-flowering plants, such as ferns, begin with spores.) You are probably familiar with seeds and may have even eaten a few, such as sunflower or pumpkins seeds. A seed has a protective coating called the shell. The shell contains everything needed to start a new plant. Inside the seed coating is an embryo, which will become the new plant, and the endosperm, which provides the nutrients for the embryo. Seeds are dispersed, or spread, in a variety of ways. Some are blown by the wind. Others float on water. Still others are carried by birds, bees, other insects, or on the fur of animals. Some are even eaten by animals and spread through their waste. And, of course, humans plant seeds for their fruit or to make their lawns attractive. Once a seed reaches its destination, the next stage of the life cycle begins. Germination Seeds need four things to grow: oxygen, moisture, sunlight, and the right temperature. When the proper conditions are met for the seed, it will begin to sprout. The roots push their way through the seed coating and begin growing into the soil. This process is called germination. Seedlings A small, fragile young plant called a seedling will then poke its way out of the ground and start growing towards the sunlight. The seedling gets many of the nutrients it needs to grow from the soil through its roots. The seedling also gets nutrients from the sun. A plant’s leaves contain a green pigment called chlorophyll. This pigment uses sunlight, water, and carbon dioxide to produce energy for the plant in a process called photosynthesis.   Adult Plant Photosynthesis helps the seedling grow into a mature plant. The mature plant produces flowers, which ensure that the life cycle continues. A mature plant has leaves, roots, and a stem. The roots extract nutrients and water from the soil. These are carried to the plant by the stem, which also serves to support the plant. The leaves create energy through photosynthesis. The flower is the part of a plant needed for reproduction. It is made up of many different parts. The petals are usually bright and colorful for attracting insects to help with the pollination process. The stamen is the part of the plant that produces pollen. Pollen is a powdery substance, often yellow, that contains half of the genetic material needed to create a new plant.   The stigma is the part of the flower the receives the pollen. It contains the ovules of the plant. The ovules will become seeds when they are fertilized by the pollen. Pollination The process of getting the pollen from the stamen of one plant to the stigma of another is called pollination. Pollen may be carried by the wind, but it is often transported from one flower to another by insects. Some types of bats even help with the pollination process. Bees, butterflies, and other insects (or bats)  are attracted to flowers by the colorful petals. The insects drink the nectar (a sweet liquid)  that flowering plants produce. While the insect crawls around the plant drinking the nectar, it gets pollen on its legs and body. When the insect flies to another plant to drink more nectar, some of the pollen from the first plant is deposited onto the second plant. Remember, pollen contains half of the genetic material needed to produce a new plant. The ovules, located in the stigma, contain the other half. When the pollen reaches the ovules of a plant, they are fertilized and become seeds. Then, the plants fertilized seeds are dispersed by wind, water, or animals, and the whole process begins again.

Organization and Managing People Term Paper Example | Topics and Well Written Essays - 2500 words

Organization and Managing People - Term Paper Example Organization and Managing People When the launch of consultation tactics within the organization involves requesting for the other party’s assistance in the matter or altering the proposal so as to convince them that their consultation on the matter is invaluable and thus, required. Empowerment is the key to promoting employee motivation and launching power distribution to reaffirm an employee’s belief that the organization trusts his/her skills, knowledge and decision-making abilities. An example of this measure is a Finance Manager granting the Assistant Finance Manager the right to authorize daily sales reports which previously required the former’s signature. Participative management allows employees to adopt a more direct role in the entire decision-making process by setting goals and resolving organizational issues to achieve the identified objectives. It allows managers to distribute power in the company through the promotion of autonomy. A manager needs to consider the following factors to make delegation effective: providing appropriate training to employees to ensure that they are able to manage tasks, encourage managers to delegate work, boost a system of participative management in the organization. By using rational persuasion on the basis of logical argumentation and evidence a manager can ensure that his employees commit to health guidelines in a company. The same could also be achieved through the tactic of pressure as a result of which constant reminders are placed in the company to promote compliance.

Land law Assignment Example | Topics and Well Written Essays - 3000 words

Land law - Assignment Example 110,000 without explicitly stating that this was a new mortgage leaving Ben to believe that this was some form of mortgage repackaging. Ali used her accountant, Devi, to talk Ben through the mortgage papers. Devi however made it clear that Ali’s job is dependent upon his cooperation. Ali’s investment then failed and made Ben and her to default on their repayments. Their banker, Cantander Bank, initiated the move to repossess the property so as to recover the mortgage amount but Ben is unaware that he signed a second mortgage and is surprised by the move. Repossession is a legal process where an owner’s right to own a property is terminated usually because he or she has defaulted in payments1. Repossession of a mortgaged property usually occurs when the borrower defaults on the regular payment for sometime as stipulated by the terms and conditions of the lender, in this case Cantander Bank. Following the circumstances involved in this case, the bank has a right to recover the owed amount by repossessing and selling Valiant Villa. It is a straightforward case that the two, being joint account holders, make decisions jointly. The fact that the signatures of both partners were appended in the mortgage is enough evidence that each partner consented. It is not up to the bank to determine how the consent was obtained as this is a private, or even a homely, matter2. The bank can point out that it was Ben’s negligence and/or mistake that cost them their family home. A mistake is an erroneous belief that leads one to believe certain facts are true during contracting3. In this case Ben believed that they were repackaging the first mortgage of ?125,000. The law provides that a contract cannot be rendered voidable because it was caused by a unilateral mistake of this nature. Furthermore, Ben acted negligently when he signed the papers without exercising due diligence to know what he was really signing. Negligence is defined as the failure to exer cise care where an otherwise prudent person would when in a like circumstance4. While the real relationship between Ben and Ali is unclear, it is evident that there is mutual trust. The fact that they hold a joint account also shows the amount of trust and confidentiality between them. However, in matters concerning mortgaging a family home it is expected that one will take due care to read and understand the seriousness and the nature of implication of contract being signed. Ben did not do that, neither did he seek independent legal counsel if he did not understand. The bank therefore reserve the right to reposes the property, sell it and recover the amounts loaned to Ben and Ali. However, Ben can use undue influence as his defence and prevent Valiant Villa from being repossessed by Cantander Bank. This is because the courts of law are courts of conscience, they not only apply the law to the letter but also apply them in such a way that justice is served as in the case of Royal Ban k of Scotland v. Etridge 5. The courts have the obligation to determine how consent was obtained. The manner in which the intention to enter the contract was secured is material in cases of repossession especially of a family home. If the court finds out that the consent was obtained through unacceptable or improper means then the court should not allow such a transaction to stand6. In this case, Ben’s can use the undue influence defence by arguing that his consent was not secured in a proper manner. Since Ali knew that Ben did not approve of her

Analyzing the series of events that occurred, involving Karemore Best Essay

Analyzing the series of events that occurred, involving Karemore Best Health NHS Trust and St. Patchup Hospital NHS Trust - Essay Example It follows with a series of recommendations for change to avoid such mishap from recurring at the two hospitals. This would also serve as a reminder towards other health care institutions towards strict compliance of standard procedures, and a guide to prevent such accident to occur in their organization. As requested by the Chief Executives of both Karemore and St. Patchup Hospitals, the author of the present report is a Radiology Services Manager of a hospital outside Prosperham City. Summary The persons directly involved in the unfortunate circumstance are: (1) Mrs. Wanda Doff, the patient, (2) Di Gital, a radiographer employed at St. Patchup from an agency, (3) Karl Amity, a radiographer at Karemore who took the patient’s radiology exams, and (4) Dr. Penny Drops, anesthetist at Karemore involved in Mrs. Doff’s operation. Mrs. Doff died of respiratory and cardiac arrests in the middle of a hip replacement operation at Karemore Hospital. Due to complaints of right hip pain approximately 6 months before the operation, Mrs. Doff underwent a chest radiograph antero-posterior (AP) position at St. Patchup Hospital, which was conducted by Di Gital.... That same evening, Karl Amity once again conducted the examination but mixed up results of the said patient with another. Seeing that the results were normal, Dr. Drops agreed that Mrs. Doff could go into the theatre and proceeded with the operation. Complications aroused, however, leading the patient into respiratory and cardiac arrests where practitioners were not able to resuscitate her. Range of Incidences and Mistakes Upon investigating the incident, it can be traced that lapses started with the imaging departments of both Karemore and St. Patchup Hospitals. Initially looking at St. Patchup Hospital, the lack of supplies - in this case batteries for the hoist - triggered the sole personnel left in the room, Di Gital, to aid Mrs. Doff. This, however, is not an excuse since patient safety is always a priority, and Di Gital should have realized the risk placed upon the patient in the process of lifting her alone. Furthermore, several other lapses are perceived from Karemore Hospita l. Taking into consideration that Karl Amity has been a qualified radiographer for several years, it is expected that he knows how to conduct the procedures adequately and follow given protocols. However, the patient was exposed to excessive radiation dose because of Mr. Amity’s mistakes with centring and lateral hip projection. Dr. Drops also committed a mistake in the act of ordering another chest x-ray without reviewing the patient’s records which could have revealed all the previous examinations she has undergone. Additionally, Karl did not question the doctor’s order for another x-ray even in the knowledge that he has met the patient earlier that morning. To make matters worse, he interchanged the results of the patient with another woman’s, thereby giving wrong results

Writing Style is Important Essay -- Writing Style Styles Essays

Writing Style is Important Contrary to popular conceptions of the term ‘style’, I have found that in the context of this class, as well as in the context of the books â€Å"Style Toward Clarity and Grace† by Joseph M. Williams and â€Å"The Elements of Style† by Strunk and White, that ‘style’ is not style in the sense that it is the way I write (in such as way as ‘everyone has their own unique style’). Style encompasses many elements to writing a cohesive, clear paper. However, I feel that in order to write a clear cohesive essay or paper, I must write in my own way, a way that I am familiar with. This may seem like it goes against something that would be in â€Å"The Elements of Style,† but it is not. Strunk and White clearly say in their book, â€Å"Write in a way that comes naturally.† (Strunk and White, 70). Even though Strunk and White say to write naturally, they contradict themselves later in the book. â€Å"Prefer the standard to the offbeat.† (Strunk and White, 81) is rather contradictory because I feel that if someone is going to write in a way that comes naturally, it can be offbeat, it can be different, and it can still be understood. Also, imaginative writing or experimental writing can help and create a better writer. Ravi’s Blog also addresses this issue, â€Å"It is much easier for me to be given a topic and write a formal essay on it than to push my writing outside conventional forms and really try something new. In order to succeed in the professional world, a writer needs to have a proficient command of standard English, but in order to explore ourselves and our relationships to one another, writers must find ways to break the mold.† (ravieng328.blogspot.com, October 7th entry). I think Ravi, as ment... ...at a lot of those rules are relative. That is to say my idea of wordy and breezy would be completely different then that of someone who will be reading this. I used to refer to my ‘style’ as the way I would write and the way my writing would be read personally. Now, after reading these books, I can see that there is more to style than just my own personality coming out in the writing. I can still have style, but I also need a different kind of style. I need the kind of style that is standard and recognized so that I will be more cohesive, more clear and write a better academically constructed paper.

Magnesium Oxide Chemistry Report Essay

In chemistry, compounds can be distinguished by using the empirical formula. The formula provides the simplest positive integer ratio of elements in a compound. The empirical formula is largely useful in determining the ratio of elements within ionic compounds where the structure is of a non-directional nature of bonding where any ion at any time could be surrounded by 4, 6, or 8 oppositely charged ions. This creates a pattern of endlessly repeating lattice of ions they do not exist as a free unit of atoms but in crystal lattices with repeating ions in specific ratios which is why empirical formula is used as a form of identification for defining an ionic-bonded substance. Calculating the empirical formula: To calculate the empirical formula for when two reactants undergoes a chemical reaction, the following 5 steps should be taken: 1. Record the masses of all the elements present in a given compound. 2. Convert the masses into moles (dividing by atomic weight in grams). 3. Then divide through by the smallest number of moles to get a ratio. 4. It the numbers are not whole numbers, multiply by a suitable small factor to get a whole number. 5. Finally, round off the numbers in the previous step if applicable to get the prime numbers which indicates the empirical formula. To demonstrate with a simple example; The molecular formula of butane is C4H10, however as the ratio of carbon atoms to hydrogen atoms is 4:10; it can be reduced to the ratio of 2:5. We can see that it is the simplest ratio while remaining as an integer. Butane can now be represented in empirical formula as C2H5. Regarding the Mole and its formula: The mole is the quantity of a substance which contains as many elementary units (atoms, ions, molecules) as there are atoms in exactly 12 grams of carbon-12 isotope. A mole of an element is the mass in grams that is numerically equal to the atomic weight. Also, a mole of a compound is the mass in grams that is numerically equal to the molecular weight. In simpler words; A mole of a substance is simply the atomic / molecular weight in grams. eg; A  mole of copper (atomic weight 63.6) is 63.6grams. Therefore in a diagram; The number of atoms or molecules in a mole of any substance is the Avogadro Constant which is 6.02 x . The molar mass is taken to be the relative atomic mass of an element which is the average mass of atoms present in any naturally occurring element relative to the mass of one atom of carbon-12 isotope taken as exactly 12 which gives formula weight (sum of the atomic weights of the atomic species as given in the stated formula for the compound.) The quantitative stoichiometric relationships governing mass and amount is used in the following experiment regarding the combustion reaction of magnesium metal. Magnesium is reacted with oxygen from air in a contained crucible, and the masses before and after the oxidation is measured. The resulting masses are used to calculate the experimental empirical formula of magnesium oxide, which is then compared to the theoretical empirical formula. A crucible and Bunsen burner will be used to heat magnesium metal for burning. Equipment: AIM: The purpose of this experiment is to perform an experiment of the combustion of Magnesium and gather precise and accurate data of masses and thus find the number of moles of the substance through the stoichiometry mole equation in order to evaluate the empirical formula of Magnesium Oxide. METHOD: 1 The Bunsen burner was set up with the tripod. The pipe clay triangle was placed over the tripod, ensuring that it is secure. 2. The crucible containing the magnesium was positioned in the pipe clay triangle securely with the lid on. 3. The gas was turned on and the Bunsen burner ignited to a blue flame. 4. The crucible was fired strongly for 5minutes until the bottom of the crucible glowed red over the blue flame to rid of contaminants. 5. The flame was removed and to cool the crucible with lid.  6. A piece of magnesium about 5 cm long was cut.  7. The surface of the magnesium ribbon was thoroughly cleaned with steel wool and its appearance was recorded 8. The cooled crucible and lid was weighed  (1st mass to 2dp) 9. The cleaned magnesium was coiled to fit inside the same crucible and covered with the same lid. 10. The crucible containing the magnesium with the lid on was weighed. (2nd mass to 2dp) 11. The crucible containing the magnesium was positioned without the lid onto the pipe triangle setup, ensuring its security. 12. The gas was turned on again and the Bunsen burner was ignited to a red flame (air hole fully open). 13. As the magnesium began to glow, the crucible was covered with its lid carefully with tongs. 14. Heat strongly for about 10 minutes lifting the lid a little VERY carefully occasionally to admit oxygen. 15. Keep heating and lifting the lid until ALL the magnesium turns into gray-white powder or until no further reaction can be witnessed to ensure complete reaction (for around 5 minutes) 16. Turn off the gas and allow the apparatus to cool.  17. Weigh the completely cooled crucible containing magnesium oxide with the lid carefully. (3rd mass to 2dp) RISK ASSESSMENT: Wear safety glasses. It is important to have eye protection during the combustion of Magnesium as the burning Magnesium in the crucible produces a very bright light which emits a harmful intensity of UV light which can cause eye discomfort or damage. Do not inhale the smoke produced when Magnesium is burned. Magnesium Oxide smoke can cause irritation in the nose, eyes and lungs and in large amounts, may cause metal fume fever. Use tongs at all times when handling hot objects. Careful handling of hot equipment such as the crucible and its lid during the heating is important as the very high temperature can burn skin due to improper or insecure handling. Do not cool the crucible or lid under cold water immediately after heating. This can cause the equipment to crack and the shards may easily pierce the skin. If the crucible crack during the experiment, it is vital that the person discontinue any progress with the experiment and proceed to clean the broken equipment away immediately and place into the broken glass bin. RESULTS: MASSES BEFORE HEATING AFTER HEATING Mass of Magnesium 0.08g n/a Mass of oxygen n/a 0.05g Mass of Magnesium Oxide n/a 0.13g Mass of crucible + lid 24.36g 24.31g Total mas of Mg oxide in crucible + lid: n/a 24.44g Total mass of crucible + lid + magnesium: 24.39g n/a Percent composition of Magnesium in compound: Mass of Mg in 1 mole/ Mass of MgO in 1 mole  % composition of Oxygen in compound: Upon observation, the 5cm Magnesium ribbon had a slightly greasy texture and a brittle and coarse surface. It had a hazy, dark metallic sheen to its appearance. After polishing its surface front and back thoroughly with steel wool, there was a change in its appearance. It had a shiny and glossy silver lustre with a smooth clean surface, no longer feeling waxy. The steel wool’s purpose was to remove the oxide layer of carbonate and sulphate which has coated the Magnesium ribbon’s surface due to its slow oxidation in air with CO2 and SO2 and other possible contaminants (which may have caused the strip to feel greasy). The oxide coating on the Magnesium would have made the ribbon more resilient to ignite immediately and thus hinder the combustion  of the metal and prolong the time it takes for the metal to fully combust. The procedure of rubbing Magnesium’s surface with steel wool was beneficial in order to expose fresh Magnesium to facilitate the contact of the r ibbon with the flame quicker and thus a faster complete combustion. The crucible and lid used had minimal surface stains on the outside however it was heavily contaminated with residual substances towards the inside base. By firing the equipment under a blue Bunsen flame thoroughly, it became apparent that any moisture or volatile materials present are burnt off by 5minutes to reveal a clean crucible free of stains or moisture. The purpose of firing the crucible at a high temperature was to quickly eradicate any stubborn chemicals which may have resisted cleaning by water, as well as any moisture the crucible may hold to provide a clean and dry equipment which can ensure accuracy and validity of calculations of masses. In order to activate the reaction of Magnesium, a source of energy was needed. The flame provided a source of heat which prompted a chemical reaction to proceed. When the magnesium was supplied with energy in the crucible, it reacted with a limited quantity of oxygen by using the lid to prevent high exothermic energy (Magnesium would react vigorously if heated in the presence of unobstructed air flow) and the escape of any magnesium oxide during the combustion. It became oxidized to become an ionic compound Magnesium Oxide. After the experiment of combusting Magnesium, the residue in the crucible is observed to be in a fine white powder form of Magnesium Oxide, an ionic compound. The exothermic reaction of combusting Magnesium produced a very bright light within the crucible due to the rapid heating of the Magnesium, where it quickly absorbs energy through ionisation. Magnesium ionises to become a cation while Oxygen ionises to an anion, forming an ionic bond due to electrostatic forces. DATA ANALYSIS: In this experiment, through the combustion reaction of Magnesium, a word equation forms between Magnesium, Oxygen and the ionic compound Magnesium  Oxide. Magnesium + Oxygen ïÆ'   Magnesium Oxide When ignited, magnesium has reacted with oxygen to form the products Magnesium Oxide. By taking the mass of equipments’ used and its mass during and after the reaction, the mass of Magnesium, Oxygen and Magnesium Oxide can be calculated. The mass of the reactants should very closely or mirror the mass of products by Law of Conservation of Mass. COLLECTING MASSES: (mass 1) Crucible + lid = 24.31g (weight after ridding of visible contaminants on crucible) (mass 2) Crucible + lid + magnesium = 24.39g (weight after polished magnesium is placed in fired crucible + lid) (mass 3) Crucible + lid + product = 24.44g (weight of reacted substance MgO in the crucible with lid) To calculate the mass of Magnesium metal = Mass 2 – Mass1 = 24.39g – 24.31g Mass of Magnesium = 0.08g To calculate the Mass of Oxygen incorporated = Mass 3 – Mass 2 (the increase in mass corresponds to the mass of oxygen) = 24.44g – 24.39g Mass of Oxygen = 0.05g To calculate the mass of oxide product formed = Mass 3 – Mass 1 (to validate through law of conservation of mass) = 24.44g – 24.31 Mass of Magnesium Oxide = 0.13g Now that the mass of each substance which took part in the reaction is found, the number of moles can be found through the relationship below. Number of Moles = Mass / Molar Mass Or N = The number of Moles can be calculated by knowing the mass of individual substances in the experiment divided by the molar mass (given on the periodic table as atomic mass number) to experimentally determine empirical formula for the ionic oxide. CONVERTING TO MOLES: Number of Moles of Magnesium: N = 0.08g / 24.31g/mol = 0.00329082692 moles Number of Moles of Oxygen: N = 0.05g/16x2g/mol (oxygen is doubled as it exists as a diatomic molecule) = 0.0015625 moles DIVIDE BY SMALLEST MOLE VALUE The number of moles of Magnesium is larger than the number of moles of Oxygen: 0. 00329(to5dp) moles > 0.00156 (to5dp) moles By dividing each by the smallest mole value of 0.00156 of Oxygen, Magnesium and Oxygen mole ratio is calculated respectively. Magnesium Mole ratio Oxygen Mole ratio = 2.11(to2dp) = 1 Multiply UNTIL WHOLE: The next step is to multiply any decimal numbers by a small whole number and do the same for the other whole number ratio until the decimal number reaches a near whole number (which can then be rounded up). Magnesium Mole ratio is in a decimal number of 2.11, and as it is very close to 2(with 0.11 extra of being a whole number), the number 2.11 is round down to 2 so the process of multiplying until whole is omitted. We obtain the mole ratio as follows: Magnesium : Oxygen 2 : 1 With 2 moles of Magnesium reacting with 1 mole of Oxygen, this should suggest 2 moles of MgO after balancing the equation. 2Mg(s) + O2(g) → 2MgO(s) To confirm, the law of conservation of mass is applied which states that in a balanced equation, matter is conserved: Total mass of reactants = Total mass of products Thus, by adding the mass on the left hand side (reactants), it should equal the right hand side (product). Magnesium + Oxygen = 0.08g + 0.05g  Magnesium Oxide = 0.13g It is found that there is no difference in mass between the left side of 0.13g of Magnesium + Oxygen to the right side of 0.13g of Magnesium Oxide in the equation considering the possibility of experimental errors, which represents a positive outcome as an theoretical equation is established and proved to be true. The empirical formula for Magnesium oxide is MgO, which is the correct formula and thus the aim of this experiment has been met. DISCUSSION: The experiment demonstrated the ability for a substance to exist in the empirical formula composition as the simplest ratio of elements present in the compound. It also demonstrated quantitative stoichiometric relationships between the number of moles, mass and molar mass in a chemical reaction. The theoretical result for the combustion product of Magnesium and Oxide is MgO, which in comparison to the experiment result of MgO was proven to be the same. This experiment had demonstrated the basic chemical reaction and the change in states between elements in order to form a stable ionic compound. Through the ionic bond between a metal and a non-metal, Magnesium Oxide was the product of two reactive elements Magnesium and Oxygen. Theoretical laws of conservation of mass and constant composition, lead to the formation of a relationship between the reactants (Magnesium and Oxygen) and product (Magnesium Oxide). The total mass of the products of a reaction must equal the total mass of the reactants. (0.8+0.5 = 0.13) The coefficient of a substance indicated the amount of portions each substance existed in, based on the law of conservation of mass. (2 moles of Magnesium, 1 mole of Oxygen, and 2 moles of Magnesium Oxide). And lastly, the empirical formula of a compound gave the lowest whole-number ratio of the atoms that is the identical with the mass ratios measured by experiment. (MgO) Any portion of a compound will have the same ratio of masses as the elements in the compound. Metal and a non-metal > reaction of 2 substances taking place> Ionic bond of elements>changes in states and formation of a stable compound >the construction of an unbalanced chemical equation -> evaluation of masses of the reactants to products> the law of conservation of mass/and constant composition ->the masses of left side  equals right side provide moles to balance the overall equation >establish empirical formula for end product. 3 experimental errors that may have effect on result Magnesium Oxide forms fumes which may escape the crucible when allowing a passage for oxygen to pass when the lid is lifted. Incomplete combustion of Magnesium (as no stirring rods was used to check/sift through the oxide to prevent calculation errors) Unthorough firing of crucible and lid (due to contact between tongs and crucible, certain areas may be missed) 3 improvements to method to improve results: Monitor the reaction of Magnesium with oxygen carefully, and keep the lid in place on the crucible containing the magnesium instead of off in step 11. Heat the magnesium for five minutes longer, lightly rotating the crucible at its base to ensure complete combustion. Fire the crucible and the lid twice to ensure that its’ completely dry and clean. CONCLUSION: An experiment was performed to calculate the empirical formula of magnesium oxide by comparing the masses of solid magnesium metal to the magnesium oxide solid product in a crucible. The concept of stoichiometry mole equation leads to finding the empirical formula of magnesium oxide. One major finding during the experiment was that burning magnesium caused its mass to increase as it reacted to oxygen. The amount of mass increase is proportional and able to be calculated through weighing the mass of product Magnesium Oxide and subtracting the original Magnesium mass to calculate the mass of Oxygen which partook in the combustion. The Empirical formula had indicated the proportion of Magnesium to oxygen (1:1) and identifies the compound to be Magnesium Oxide. The balance was very accurate in taking precise measurements of masses and the supervision of the experiment during the burning had been careful to prevent any loss of Magnesium Oxide mass to escape which in turn caused my mass results to apply to the law of conservation of mass without any experimental errors.

The Freedom Of The United States Essay - 854 Words

Freedom House was established in 1941 in the United States and focused first on the threat to freedom represented by Nazism. After the war, in its own words, it â€Å"took up the struggle against the other great twentieth century totalitarian threat, Communism† and defined its mission as working for the spread of democracy and human rights in the world. Indeed, one of the instruments developed by Freedom House in order to spread its mission is the’s press freedom index, which has not changed practically at all since its creation in 1980. Due to this methodological continuity for over three decades, this index is amply used and quoted within and outside academia (Becker et al., 2007; Holtz-Bacha, 2004; Behmer, 2011). During the analyzed period 2010-2014, the questionnaire suffered minor, but significant changes: as of 2011, the word â€Å"bloggers† was introduced in some of the questions, together with professional journalists. The instructions for answering another question indicate that the respondent should â€Å"consider written, audio visual and internet media†. Freedom House included the latter in the measurement as a response to criticism of its exclusive focus on traditional media and disregard of digital media (Burgess, 2010). Freedom House uses a scale of 0 (best score) to 100 (worst score) based on 23 questions and 109 indicators divided in three categories: legal environment (a country may obtain up to 30 points), political environment (maximum of 40 points) and economicShow MoreRelatedThe Freedom And Freedom Of The United States1499 Words   |  6 PagesKnowing the Meaning of Freedom Freedom and liberties are the most popular and significant topic in the United States.
