Oxalate Lab Essay - 609 Words

Dr. Hjorth-Gustin Chemistry 201 Lab November 8th, 2010 Synthesis and Analysis of Iron(III) Oxalate Complex Discussion This experiment initially involved the synthesis of an iron (III) oxalate complex with the general formula Kw[Fex(C2O4)y] zH2O. The variables x, y, and z were determined through the duration of the entire experiment. Part 1 involves the synthesis of an iron (III) oxalate complex. The iron is first presented in its Fe2+ form, so it must first be oxidized to Fe3+ before the oxalate ion will readily bind to it. Hydrogen peroxide is the oxidant of choice: 2Fe2+ (aq) + H2O2 (l) + 2H+ (aq) --- 2Fe3+ (aq) + 2H2O (l), in acidic solution. The oxalate ion is then free to coordinate to the Fe3+ ion, forming a†¦show more content†¦Part 2 of this experiment invoked the use of redox titrating to determine the oxalate content (C2O42-) of the salt. An aqueous solution of the iron oxalate salt is prepared for titration, and the oxalate content is found through analysis by measuring the volume of titrant. Part 3 of the experiment utilized Spectrophotometry to determine the iron content in the iron (III) oxalate complex. The results were combined with findings from Part 1 and Part 2 to determine the empirical formula and percentage yield of the compound synthesized in Part 1. Spectrophotometry is a routine laboratory test that has the added advantage of being able to analyze multiple samples in a short amount of time. The most efficient way of determining concentration is to prepare a set of standard solutions of known concentration, record the absorbance readings at a fixed wavelength, and plot the absorbance vs. concentration data. The wavelength of 520 nm was selected for experiment Part 3 because this is the maximum absorbance for the iron (III) ion. The Beers Law Plot that was graphed came out to be linear with an equation of: Absorbance = 5.395 x 10^3(Fe^+2-Bipy) - 0.0014. The empirical formula that was determined was different from that of the â€Å"true† compound mentioned. The empirical formula determined was: K3[Fe(C2O4^-2)3] 3 H2O If had there been a better alternate method to determining the ironShow MoreRelatedEssay about Determination of the Composition of Cobalt Oxalate Hydrate1041 Words   |  5 PagesComposition of Cobalt Oxalate Hydrate Experiment 12 Robbie Kinsey Partner: Debnil Chowdhury Chem. 1312-D TA’s: Russell Dondero Sylvester Mosley February 9, 2000 Purpose The purpose of this lab was to determine the percent cobalt and oxalate by mass, and with that information, the empirical formula for cobalt oxalate hydrate, using the general formula Coa(C2O4)b.cH2O.

Why Is Diotima a Woman Essay - 825 Words

Diotima, Socrates great teacher from the Symposium, a work by Plato was one of the most influential women thinkers of all time, whether she was a real person or a literary fictional character. She related to Socrates the theory of love that he described to the partygoers at Agathons banquet, a celebration of Agathons victory at the competition of Dionysis in Athens and of Eros. Before we search for the idea of why Diotima is a woman, we should first discuss a little about her. We know that, if she were an actual person, she would have been born around 470 BCE and died around 410 BCE. She might have been a priestess from Mantinea. Now if she was a real priestess or poet is uncertain. There is archaeological evidence, plus the fact†¦show more content†¦The first is obvious. Diotima is a woman because she is not a man. If Diotima had been portrayed as a man then Socrates would have been seen as having been initiated into the mysteries of erotic desire by an older and wiser male. This would have inevitably suggested to Platos contemporaries that Socrates owed his deep understanding of the nature of the erotic (Symposium 177.d) to the passionate attention of a former lover. By having a woman educate Socrates in the ways of Eros, Plato avoided the suggestion that the he was Socrates real lover. Plato wanted to rule out that he and Socrates were sexual lovers, rather than just merely platonic lovers. (Gould p.193) Plato strenuously wanted to avoid this, not only because it would have lent the stamp of Socratic approval to a social practice for which Plato himself entertained the liveliest mistrust but, more importantly, because it would have had the effect of valorizing the Athenian institution of paederasty (Sexual relations between a man and a boy (usually anal intercourse with the boy as a passive partner)) on the very grounds on which Platos Pausanias, earlier in the Symposium, had celebrated. (181.c-d3) We can further this by saying that if Pla to had represented Socrates as having benefited from the erotic expertise of a mature male, the principle underlying Socrates later rejection of Alcibiades (Symposium 222.c3) would have been obscured, and Plato would haveShow MoreRelated Why is Diotima a woman?

Abuse Of Children In Detained In Youth Detention Centers - samples

Question: Discuss about the Abuse Of Children In Detained In Youth Detention Centers. Answer: This is to draw your attention towards the routine abuse of children who are detained in the youth detention centers in the Northern Territory. I work as a social worker in the Northern Territory and is associated with the Correctional services that is provided to the juveniles. It is astounding to believe that in Australia, children as young as 13 are locked up in solitary confinement and children who are 10 years old are locked up in the prisons. The youth justice system of the country is a set of processes that manages young people and children who are alleged to have committed an offence. When the police investigate the crime alleged to have been committed by the young children, they are introduced to the youth justice system for the first time. The course of legal action that could be undertaken by the police includes court actions and non-court actions such as counseling, cautions or infringement notices. It is a well-known fact that the youth justice system in Australia is based on the concept that detention for young people should be the last resort for all the young people and this concept is consistent with the United Nations Convention on the Rights of the Child (UNCRC) and the United Nation High Commissioner for Human Rights 1985, 1989). The significant feature of the youth justice system is supervision of the young people either within the community or within the detention facilities[1]. The UNCRC stipulates that young people should be detained and deprived of their liberty as a last resort[2]. However, in practice; children are confined to an isolation wing where they do not have any access to running water or sunlight. The cells are ghastly and seemed to be from the medieval era. Further, the wide publication of the CCTV footage and the images that revealed the abuse the children were being subject to routinely, while they are detained in the youth detention centers. The treatment that was provided to the detainees, who were 10 to 13 years of age, amounts to a breach of the human rights. In supporting this argument, I have learned about the issues that the young children are facing within the youth justice system from other media articles, TV Programs that have witnessed such abuse and violation of the human rights of the detainees. The Australian TV program, Four Corners, from the Australian Broadcasting Corporation presented a report on the barbaric treatment that the children in the Don Dale Detention Centre undergo while in detention. The images published along with the report defy belief but subjects the detainees to inhuman treatment. The Don Dale Detention Centre had six boys who were being held in the isolation wing. The counselor for these young offenders asserted that although there was sign of life in the detention centers but the lawyers had no knowledge who was in there and for how long the children were being held in such isolation wing. The Four Corner made revelation about the unexpected truth about the children behind the bars. The children are assaulted, stripped naked and tear-gassed. The children had nowhere to run and were death-scared. The treatment was inhuman, cruel and if any person would have treated their own children that way, the authorities would have taken the children from such person on grounds of cruelty. The images reveal that the youth justice system of Australia which was based on the concept that the children shall be deprived of liberty as a last resort, has become a system that punishes the young offenders instead of rehabilitating them by locking up 10 years old children and by keeping the 13 year olds in a solitary confinement[3]. The primary relevant conventions related to the juvenile justice in Australia are the UNCRC, International Covenant on Civil and Political Rights (ICCPR), Convention Against Torture (CAT) and the Convention on the Rights of Persons with Disabilities (CRPD)[4]. In the presence of such clear legal framework that stipulates human rights of children within the juvenile justice system should be respected, the question that arises is to what extent Australia does complies with these legal rights in practice[5]. As per the reports published in The Conversation, after the wide publication of the report and images of the barbaric treatment that is provided to the detainees, a Royal Commission to investigate into the conditions of the juveniles within the Youth Justice System in the Northern Territory. In the report by the Four Corners, the juveniles were being detained in the isolator wings for 23 and half hours a day and most of the boys have lost all sense of time. The cells are extremely hot, no air-conditioning, no fans no light. If the boys ask for the reasons or the date or time, the officers use tear gas on them. They are often shackled, dragged and sprayed with a fire hose in the name of the applying reasonable force to prevent the juveniles from acting violently. I being a social worker would like to make some recommendations, which would assist the department in improving the conditions of the detention centers. The youth justice system must replace the punitive approach with other youth justice models that promotes therapeutic and rehabilitative approach. The Department of Youth Justice System, must make significant efforts to identify and respond to the issues faced by the victims and the trauma that the young people undergo within the youth justice system. Cultural considerations should be entrenched at all stages of youth justice proceedings. These recommendations would enable the Department to reinstate the concept that lays down the foundation of the Youth Justice System, that is, to rehabilitate the young children instead of subjecting them to inhuman treatment violating their human rights.

Goldman on Plain Sex free essay sample

Notes on Alan Goldmans Plain Sex Two Lessons about Ethical Thinking (1) Many ethical disagreements hinge upon disagreements about facts, not about moral principles. (2) Being a moral objectivist neednt mean being morally conservative. Both lessons help limit the appeal of moral relativism. ********************** (1) Many ethical disagreements hinge upon disagreements about facts, not about moral principles. Goldman claims that views about immoral sexual behaviour are rooted in our definition of sexual behaviour desire. Goldman criticizes Means-End Analyses i. The end (i. e. , purpose) of sex is reproduction. ii. The end is the expression of love iii. The end is communication iv. The end is interpersonal awareness. Why? Should we reject these analyses? Goldmans reason for rejecting those analyses: Theory (i) mistakes natures purpose for reproduction for our own. First of all, why should we think that nature really has any purposes at all? Only conscious things can have purposes, but nature isnt a conscious thing. We will write a custom essay sample on Goldman on Plain Sex or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Secondly, even if nature does have purposes, why should consider them  our  purposes? For example, if nature has purposes then probably the purpose of eating (from natures point of view) is nutrition, but we often think of eating differently. To us, the purpose is not just nutrition but also enjoyment. Theories (ii) (iv) mistake things that may, in particular cases, be associated with sex for things that are essential to sex. For example, Goldman thinks that sex  may  in particular cases be a way of expressing love, but it doesnt have to be. Are these convincing reasons for rejecting the these analyses? Goldmans Analysis:   sexual desire is desire for contact with another persons body and for the pleasure which such contact produces; sexual activity is activity which tends to fulfill such desire of the agent. (268) Sex is plain sex and nothing more. Is this the right account? How will the account you endorse affect your position on sexual morality? Consider:   once you define the purpose of sex, then it seems make sense to consider sex that doesnt serve that purpose as perverted, immoral sex. Think about the implications of each of the above analyses of sex for what counts as immoral sex. Notice how disagreements about something as seemingly uninteresting as the definition of sex can lead to substantial moral disagreements. ************************* (2) Being a moral objectivist neednt mean being morally conservative. Goldman considers both Deontological (i. e. , Kantian) Consequentialist (i. e. , Utilitarian) ways of considering sexual morality. (a)  Utilitarianism The moral rightness and wrongness of an action is determined by how much happiness it produces in total. Thus, the rightness or wrongness of   a sexual act is a function of how much happiness is produced by the act. What implications does this view have for sexual morality? (Note: Goldman seems to disapprove of utilitarianism. ) We might suggest it will lead to a fairly liberal view of sexual morality. With some limitations, if those involved in a sex act fully consent to it, its likely to lead to an overall increase in happiness, so the sexual act is morally OK. What might those limitations be? (b)  Kantian Morality The Categorical Imperative:  Ã‚  Act only according to that maxim [i. e. , rule] whereby you can at the same time will that it become a universal law. An Alternative Formulation of the C. I. :  Ã‚  Always treat others as  ends in themselves, not simply as the means to an end, i. e. , never just use people. What implications does this view have for sexual morality? Again, it might be thought to lead to a liberal view of sexual morality. With some limitations, so long as people fully consent to a sexual act no one is being treated simply as a means to an end so the act is morally OK. What might those limitations be? Here, the thing to notice is that both of these  objective  moral theories seem able to support quite liberal views about what are morally acceptable ways of behaving. The lesson here is that one can be a moral objectivist and have liberal moral views at the same time. ******************************* The question to think about for the assignment:   Is the view of sex that Goldman presents correct? [Philosophy 1200]

It is also a controversial theory that some people came to America from across the Pacific Ocean via boats, although this theory is much less supported. Asian tribes probably first came across the land bridge following migratory hears of animals, and once the ice age ended, and the glaciers melted, the tribes were marooned in North America. Over time, these tribes dispersed and traveled as far as South America, forming their own cultures and some building great empires such as the Aztecs, the Mayans, and the Incans. We will write a custom essay sample on American Pageant Chapter 1 Summary or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The Earliest Americans When Mexican natives developed wild grass into corn, it allowed tribes to establish permanent settlements, ultimately leading to the birth of centralized Aztec and Incan nation-states as well as other native tribes to grow in number and technological advance. This new process of cultivating corn spread throughout America, allowing tribes all over the continent to settle in one place and advance their population, although most tribes in North America never progressed into empires like the Aztecs. Groups that used corn to build large tribes include the Mound Builders of the Ohio River valley, the Mississippian culture, and the southwest Anasazi. When corn cultivation reached the Atlantic coast, a method, known as three-sister farming, developed. Indirect Discoveries of the New World The first Europeans to land in the Americas were the Norse sailors who landed near Newfoundland around A. D. 1000. For the next couple of centuries, other European nations wanted to explore more of the world, particularly Asia, which held the fabled silk, spice, and drugs that they had heard about during the Crusades. After many years of long, treacherous, and expensive travel to trade for these prized goods, Europeans began wishing for a more efficient way to Asia. Europeans Enter Africa When Marco Polo returned from a twenty year trip with legends of China, Europeans started to search for a better way to get to Asia. The Portuguese developed a way to sail down the coast of Africa in 1450 with the help of their new ships known as caravels. This travel also allowed for discovery of sub-Saharan Africa, previously known only in myths and legend, which the Portuguese soon took advantage of, setting up trade posts on the west coast for slaves and gold. The slave trade became a big business, with about 40,000 slaves being traded in the late 15th century. The efficiency of running plantation with slaves was discovered, which would later influence American history immensely. This caused the relation of Africa to slaves to be established early in European history. Bartholomeu Dias rounded the southernmost tip of Africa in 1488 and Vasco da Gama reached India via this route ten years later and later returned home with a small prize of jewels and spices. Meanwhile, the empire that would become Spain rid its country of the Moors, and, wanting a part in this trade with Asia, began thinking of other ways to get there. Columbus Comes upon a New World Advancements in technology as well as spirit in Europe encouraged the desire for exploration and conquest. Christopher Columbus soon persuaded the royalty of Spain to finance his trip westward. After many long weeks at sea, his crew caught sight of land on October 12, 1942. Although he was attempting to reach Asia, he ended up landing on an island in the Bahamas. From this point on, life would never be the same in Europe, America, or Africa. When Worlds Collide Upon exploring the new land, Columbus’s crew was introduced to strange, exotic organisms they had never seen before. The old world and the new world were introduced for the first time. This led to an exchange of organisms from one world to the other, both intentional, such as potatoes and corn, and unintentional, such as diseases. The new world offered the old world gold, silver, corn, potatoes, pineapples, tomatoes, tobacco, beans, vanilla, chocolate, and syphilis. The old world also gave to the new world; new species include wheat, sugar, rice, coffee, horses, cows, pigs, smallpox, measles, bubonic plague, influenza, typhus, diphtheria, and scarlet fever. Slaves from Africa were also brought to the New World. The Spanish Conquistadores Spain and Portugal made the Treaty of Tordesillas to split the land, which gave Spain the large chunk of land in the New World. All throughout the 16th century, Spain rose to prominence as an empire to be feared. Conquistadores traveled throughout the Americas, conquering lands in the name of Spain, for the Glory of God, as well as for gold and silver. In 1513, Vasco Nunez Balboa stepped into the Pacific Ocean on the west coast of the America’s and claimed everything on it’s shore in the name of Spain. Later in 1519 Ferdinand Magellan set of with 5 ships, one of which would return home and be the first to ever circumnavigate the world. Other Spanish explorers set off to North America. Ponce de Leon would be the first to explore Florida. Francisco Coronado set off to find fabled cities of gold, but unfortunately only came across small adobe houses. Hernando de Soto set off in search of gold with 400 armored men and went from Florida to just west of the Mississippi River, where died of wounds and fever. Francisco Pizarro conquered the Incas of Peru in 1532. By 1600, Spain was extremely rich from treasures found in the new world. The massive increase in silver and gold led to a revolution in the economic system that would become similar to modern day capitalism. The West Indies became a place for New World travelers to locate and organize themselves, as well as posts for preparing for battles with Native tribes. A form of slavery developed in which the Spanish government commended Indians to explorers as long as they converted them to Christianity. The Conquest of Mexico In 1519, Hernan Cortes set off to Mexico from Cuba with 11 ships of men and horses. He acquired a slave girl and a Spaniard who had been enslaved by a Mayan-Speaking tribe who allowed him interpretation of the Aztecan language. When he arrived in Teotihuacan, Montezuma received him as a god and gave him all the gold he requested. Over time, the Aztecs became tired of his constant greed and on June 30, 1520, the Aztecs attacked Cortes and his men. They retreated, and after a counter-siege and a smallpox epidemic, they conquered Teotihuacan. The Mexican population dropped from 20 million to 2 million with the Spanish invasion. Cortes also brought his culture and created a blended race known as mestizos. The Spread of Spanish America Half a century from the discovery of America, hundreds of Spanish cities were founded in the New World, populate by 100,000 Spanish men. Scholars studied at American universities. Meanwhile, the English had sent Giovanni Cabot to explore the North American east coast, while the French Giovanni da Verrazano and Jacques Cartier made themselves known as explorers of the New World. The Spanish began to fortify and settle their North American borderlands with attempts including the construction of St. Augustine to block the French and protect the Caribbean sea-passages. Spanish conquistadores also started to travel upwards to modern day Southwest U. S. They conquered the native tribes and found fur and gold. However, their main mission was in the name of the Church, to convert Native Indians to Christianity. This led a rebellion by the Indians called Pope’s Rebellion in 1680. The Pueblo rebels destroyed every Catholic Church in the region as well as killed many priests and Spanish settlers. The Spanish began around 1716 to establish settlements in Texas as a direct result of the French expedition in 1680 down the Mississippi River led by Robert de La Salle. Juan Rodriguez Cabrillo explored the California coast in 1542, although nothing of importance was found, and California remained unexplored for the next 2 centuries. In 1769 Spanish Missionaries led by Father Junipero Serra founded at San Diego the first of a chain of twenty-one missions that wound up the coast as far as Sonoma, north of San Francisco Bay. These missions took in Native Americans and converted them to Christianity, although most of them didn’t last long due to disease vulnerability.

Controversy of Cloning essays

Controversy of Cloning essays Throughout the past century, the United States as well as many other countries around the world have made astonishing advances in technology. Many of the concepts and devices that are so common to us today, were once illustrated only in the plots of science fiction films. Some of these advances are so complex that even the movie industry lacked the imagination to conjure them up. One of these amazing yet controversial new concepts is our ability to clone humans. The issue of cloning is at a height right now, sparking debates between nearly everyone. Supporters of each side have legitimate facts to back up their argument. It is easy to see the appeal to cloning when it comes to medical technology, due to the mounds of benefits it would offer patients. It could increase life expectancy to well over the age of 100 years through the new stem replacement that is currently being tested. If the government permits the study and use of this procedure it could cure long-standing diseases, mend damaged hearts, join severed spinal cords, and heal hearts that were harmed by strokes or Parkinsons disease. However, if you look at the grander scale of the process of creating human clones it becomes apparent that this is a new technology that we should avoid altogether. Due to the risks of deformed embryos, the unethical process of disposing of the clones when they are no longer of use, and the lack of support from our population as a whole, it is absolutely necessary that we do not pursue the The cloning of humans is essentially a bizarre idea. After all, who would want a genetically identical twin of themselves, born years later, created for the benefit science out there roaming around? On the flip side, who would want to be nothing more than a laboratory guinea pig, living a life with no true family, being monitored with little ...
