Cherokee Indians Essay - 1549 Words
Cherokee Nation Before invasion of the Americans onto Cherokee territory, the Cherokee lived in peace and harmony. Keetoowah is the name of the ancient Cherokee town in the eastern homelands, said to be the ââ¬Å"Mother Townâ⬠of the people (Conley 18). Many of the Cherokee Indians originated here according to the traditions. They referred themselves as Ani-Kituwagi, meaning Keetoowah People, or Ani-yunwi-ya, the Real People (Conley 27). The fertile lands of the Keetoowah were filled of many resources, but as the population grew too large for the town, many people had moved out and built new towns. Overtime, many towns were built one after another. Soon, there were approximately 200 scattered tribes over vast areas that consisted of a number ofâ⬠¦show more contentâ⬠¦It jeopardized the Cherokeeââ¬â¢s clan traditional ways of a matrilineal family structure carried on for many centuries. Nevertheless, the Cherokees could do nothing about it. nbsp;nbsp;nbsp;nbsp;nbsp;Before the first known contacts, life of the Cherokee nation had grown and thrived for many years in the southeastern United States in the lower Appalachian Mountains in states such as: Georgia, Tennessee, North and South Carolina, and parts of Kentucky and Alabama. However, the first recorded contact with outsiders was Hernado De Soto in his expedition of 1540, in search of gold throughout the Cherokee county (Martin). Mr. Soto found no trace of gold and returned empty handed. The Spanish explorers noticed the Cherokee village they encountered was practically deserted. Many of the tribes would flee from the sight of the unknown. About 100 years later, Abraham Wood, a Virginian, sent two men, James Needham and Gabriel Arthur in 1673 to establish trade (Martin). One of the traders begun to establish his home among the Cherokee Indians, which didnââ¬â¢t last for long before he was killed. Even though many explorers tried to establish trades, life of the trad itional Cherokee remained unchanged as late as 1710, which is marked as the beginning of Cherokee trade with the whites (Trail of Tears). The white mans influential politics came slowly through Cherokee Country, but dramatic. From the period 1540-1786, white expansion was taking place andShow MoreRelatedThe Cherokee Indians1351 Words à |à 6 PagesIntroduction: Have you ever heard of the Cherokee Indians? Sure you have!

Nitric Acid Free Essays
Nitric acid is a highly reactive oxidizing agent used in making fertilizers, explosives, and rocket fuels, and in a wide variety of industrial metallurgical processes. It is also a component of acid rain. Its chemical formula is HNO3 and it has been known as ââ¬Å"aqua fortisâ⬠, which means strong water, to alchemists. We will write a custom essay sample on Nitric Acid or any similar topic only for you Order Now It is a transparent, colorless to yellowish, fuming corrosive liquid. Nitric acid is a strong acid and therefore it completely dissociates in water. It has a gravity of 1. 41 and the concentration of the hydronium ions(1) yields a pH of 0. . Its boiling point is 122C and its melting point is -42C. It was first mentioned by Pseuso-Geber, a European alchemist born in the 13th century. Described by Albert the Great in the 13th century and named by Ramon Lull, who prepared it and called it ââ¬Å"eau forteâ⬠(aqua fortis). There were people saying that it was discovered by Joseph-Louis Gay-Lussac or Johann Rudolf, but nobody knows who really did discover that. As it is a intoxicating, oxidizing acid, it reacts most with metals, but does not react with pure gold. However, noble metals could be oxidized and dissolved by nitric acid which leads to colour changes of gold-alloy surface. So nitric acid is used in jewelry shops to spot low-gold alloys ( 14 carats(2)) and to asses the gold purity. Nitric acid also reacts powerfully with most of the organic material, which may also explode. It reacts with non-metallic elements except for nitrogen, oxygen, noble gases, silicon and halogens. It oxides them to their highest oxidation states(3) as acids with the formation of nitrogen dioxide for concentrated acid and nitric oxide for dilute acid. Chromium (Cr), iron (Fe) and aluminium (Al) dissolve in dilute nitric acid, which the concentrated acid forms a metal oxide layer that protects the metal from further oxidation, and it is called passivation. Nitric acid can be made in laboratory or industrially. In laboratory, nitric acid can be made from copper(II) nitrate or by reacting approximately equal masses of a nitrate salt with 96% sulfuric acid (H2SO4), and distilling this mixture at nitric acidââ¬â¢s boiling point of 83 à °C until only a white crystalline mass, a metal sulfate, remains. Then, the red fuming itric acid obtained may be converted to the white nitric acid, which the equation is H2SO4 + NO? 3 HSO? 4(s) + HNO3(g). In view of the fact that it is a really violent and strong acid, people make this acid for many different uses. It can be used in various forms as the oxidizer in liquid-fueled rockets. The forms include red fuming nitric acid and white fuming nitric acid. Red fuming nitric acid, known as RFNA, i s a oxidizer used as a rocket propellant, which can be stored very long. It consists mainly of nitric acid, but also contains 13% of dinitrogen tetroxide(4) and 3% of water. It breaks down to a certain degree to form nitrogen dioxide. The white fuming nitric acid, known as WFNA, does not contain free dinitrogen tetroxide. It consists of pure nitric acid with 2% of water and less than 0. 5% of dissolved nitrogen dioxide. If the forms are mixed with sulfuric acid, it forms with the HF inhibitor. Nitric acid can also be used in some woodwork. In a low concentration (10% of nitric acid in water), it is sometimes used to artificially make pines and maple look older. It produces a grey-gold, old looking wood colour on wood. By looking at the usage of nitric acid, we can see that, this kind of acid has a great impact to the society and the global economy. As it is not quite expensive, and you can make it in laboratories, there were many incidents where people throw glasses containers holding nitric acid on crowed streets. Many people got hurt, the nitric acid burnt through their clothes and burn them. Concentrated nitric acid makes human skin yellow, because of a reaction with keratin(5). The keratin is the key structural material making up the outer layer of the human skin, and it is also a structural component of hair and nails. It will turn orange when neutralized. However, this acid has many usages and also helps us a lot. It helps the astronauts to fly to space where nitric acid is used in rocket fuels. It also helps us decorate our places with artificial old wood furniture. This acid creates more job opportunities in the job market as the companies need people to work for it. Nitric acid is extremely hazardous and corrosive, and mostly, a poison. Inhaling will cause you breathing problems and lead to pneumonia and pulmonary edema, which may be fatal. Other symptoms may include choking, coughing, irritation of both nose and throat, and also respiratory tract. Ingesting it can cause sudden burn or pain in the mouth, throat, esophagus, and gastrointestinal tract. It can also cause skin burns if there is any skin contact. Concentrated solutions can cause deep ulcers and stain skin a yellow or yellow-brown colour. If it gets into the eye, it is even worse, as it is corrosive, the vapors are irritating and will cause damage to the eyes including burns and permanent eye damage. Long-term exposure to concentrated vapors may cause erosion of teeth and lung damage. Long-term exposures seldom occur due to the corrosive properties of the acid. People with pre-existing skin disorders, eye disease, or cardiopulmonary diseases must be susceptible to the effects of this substance. There are rules to follow when using the nitric acid. If people donââ¬â¢t follow it, it will be very dangerous to use it. Acid rain is a form of precipitation which contains a high level of sulfuric and nitric acids. It has a pH of approximately 5. 5-5. 6. It is produced when sulfur dioxide and various nitrogen oxides combine together with atmospheric moisture. Acid rain can contaminate drinking water, damage the plants and aquatic life. It also erode buildings and monuments. If the plants are damaged, people wonââ¬â¢t be abled to see the green things again and will also affect our eye-sight. And we wonââ¬â¢t have vegetables to eat after acid rain because acid may cause many harmful effects to our body. If we still eat the vegetables, then we be sick. The government had made an effort to reduce the amount of sulfur dioxide released, but it can be produced naturally by volcanic eruptions. Nitrogen oxide can be produced by lightning strikes. Acid rain had became a political issue in 1980s, where Canada claimed that pollutants from the US were contaminating the forests and waters, so power plants were asked to reduce the amount of sulfur dioxide released. Although there are harmful effects of nitric acid, people still keep on producing nitric acid. They only reduced producing them, still shows that there are still benefits of this acid! How to cite Nitric Acid, Essay examples Nitric Acid Free Essays Copper + Nitric Acid Copper is a reddish-brown metal, widely used in plumbing and electrical wiring; it is perhaps most familiar to people in the United States in the form of the penny. (Although since 1983, pennies are actually made of zinc surrounded by a paper-thin copper foil to give them the traditional appearance of pennies. ) Copper is oxidized by concentrated nitric acid, HNO3, to produce Cu2+ ions; the nitric acid is reduced to nitrogen dioxide, a poisonous brown gas with an irritating odor: Cu(s) + 4HNO3(aq) ââ¬âââ¬â Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) When the copper is first oxidized, the solution is very concentrated, and the Cu2+ product is initially coordinated to nitrate ions from the nitric acid, giving the solution first a green, and then a greenish-brownish color. We will write a custom essay sample on Nitric Acid or any similar topic only for you Order Now When the solution is diluted with water, water molecules displace the nitrate ions in the coordinate sites around the copper ions, causing the solution to change to a blue color. In dilute nitric acid, the reaction produces nitric oxide, NO, instead: 3Cu(s) + 8HNO3(aq) ââ¬âââ¬â 3Cu(NO3)2(aq) + 2NO(g) + 4H2O(l) In the following demonstration, a balled-up piece of thin copper wire is added to about 100 mL of concentrated nitric acid; once the copper is added the evolution of nitrogen dioxide occurs quickly. Once all of the copper has reacted, the solution is diluted with distilled water, changing the solution from a dark brown to a pale blue color. This demonstration can be done with copper in the form of shot, pellets, thicker wire, or bars, but is a great deal slower than with copper wire.

Like many chemists, he had a vivid ââ¬Å"learning experience,â⬠which led to a heightened interest in laboratory work: While reading a textbook of chemistry I came upon the statement, ââ¬Å"nitric acid acts upon copper. â⬠I was getting tired of reading such absurd stuff and I was determined to see what this meant. Copper was more or less familiar to me, for copper cents were then in use. I had seen a bottle marked nitric acid on a table in the doctorââ¬â¢s office where I was then ââ¬Å"doing time. â⬠I did not know its peculiarities, but the spirit of adventure was upon me. Having nitric acid and copper, I had only to learn what the words ââ¬Å"act uponâ⬠meant. The statement ââ¬Å"nitric acid acts upon copperâ⬠would be something more than mere words. All was still. In the interest of knowledge I was even willing to sacrifice one of the few copper cents then in my possession. I put one of them on the table, opened the bottle marked nitric acid, poured some of the liquid on the copper and prepared to make an observation. But what was this wonderful thing which I beheld? The cent was already changed and it was no small change either. A green-blue liquid foamed and fumed over the cent and over the table. The air in the neighborhood of the performance became colored dark red. A great colored cloud arose. This was disagreeable and suffocating. How should I stop this? I tried to get rid of the objectionable mess by picking it up and throwing it out of the window. I learned another fact. Nitric acid not only acts upon copper, but it acts upon fingers. The pain led to another unpremeditated experiment. I drew my fingers across my trousers and another fact was discovered. Nitric acid acts upon trousers. Taking everything into consideration, that was the most impressive experiment and relatively probably the most costly experiment I have ever performed. . . . It was a revelation to me. It resulted in a desire on my part to learn more about that remarkable kind of action. Plainly, the only way to learn about it was to see its results, to experiment, to work in a laboratory. from F. H. Getman, ââ¬Å"The Life of Ira Remsenâ⬠; Journal of Chemical Education: Easton, Pennsylvania, 1940; pp 9-10; quoted in Richard W. Ramette, ââ¬Å"Exocharmic Reactionsâ⬠in Bassam Z. Shakhashiri, Chemical Demonstrations: A Handbook for Teachers of Chemistry, Volume 1. Madison: The University of Wisconsin Press, 1983, p. xiv: !!! Hazards !!! Nitric acid is extremely corrosive. Handle with care. The nitrogen dioxide produced in this reaction is poisonous. This reaction must be done in a fume hood! How to cite Nitric Acid, Essay examples
