elements is Carbon (C). Carbon is essential for life and other important areas of the world. Carbon is a non-metal, that is in a solid state at room temperature. There are many different unique properties that help Carbon do what it needs to do. Carbon is the sixth most abundant element on Earth, and used in the daily lives as oil or coal. The origin of the name is Latin, coming from the word Carbo. Carbon was date discovered is not known specifically but has been known since ancient times.…

Carbon monoxide poisoning is fatal. Carbon monoxide binds to haemoglobin at the same site as oxygen – the iron atom within the haem group – however carbon monoxide will bind with a strength 200 times that of oxygen. This means that if carbon monoxide is inhaled it was always displace oxygen within haemoglobin. If oxygen can no longer bind to haemoglobin then the respiring cells of the body can no longer receive oxygen and will eventually die. When carbon monoxide binds to haemoglobin it causes…

Fossil Fuels are organic deposits derived from decaying plants and animals that have been fossilized over millions of years. There is more to them than that however they are also hydrocarbons comprised primarily of the following elements: carbon and hydrogen and some sulfur, nitrogen, oxygen, and minerals. Different combinations of these elements are used as a fuel for our everyday lives. This paper’s purpose is to explain some of the chemistry behind the use of these various fossil fuels as…

Our lives and the lives of those before us, have been unknowingly (or knowingly) shaped by elements. In The Disappearing Spoon, the author Sam Kean, discusses the wonderful world of the periodic table in depth. Within the first nine chapters of the novel, Kean explains the importance of location on the table, origin and discovery of each element, and its impact on other aspects of human life. Through various tales, the table is pulled apart and analyzed in an ingenious way. To a reader, it is…

Esterification is a Nucleophilic Acyl Substitution Reaction wherein a carboxylic acid or a derivative of a carboxylic acid accepts a nucleophile which in turns substitutes for a leaving group. In esterification a leaving group connected to the carbonyl carbon is substituted by an alkoxide ion which forms the formula RCOOR’ which is an ester. For this particular experiment the esterification used was the Fischer esterification reaction which involves a carboxylic acid and an alcohol mixed in…

fuel resources such as coal, but we are getting religion. With the right amount of will and leadership we can certainly avoid the worst ' ' ' (Marsa 124). Australia has started to work on reforms to change their nasty habits such as putting a tax on carbon, which has provided an incentive to lower the usage of fossil…

In the Acid-Catalyzed Hydration of norbornene, water and sulfuric acid were added to the C=C double bond to form norborneol. Sulfuric acid acted as a catalyst, where it was not consumed in the reaction and helped to propel the reaction forward, as it was vital in forming hydronium ion and breaking the double bond. Both the products endo-norborneol and exo-norborneol were synthesized; however regioselectivity and stereoselectivity played a role as to which product was more preferred and whether…

Beryllium General Characteristics According to Hornbostel (1991), Beryllium is a hard, exceptionally, lightweight, gray-white metal, corrosion resistant at ordinary temperatures; chemically it is related to aluminum. Other than titanium, it is the only light metal which has both good strength and a high melting point. Additionally, it is a good electrical conductor, has high modulus of elasticity, exceptionally transmit x-rays and sounds at very high velocities. Moreover, it has the ability to…

not rust or stain like normal steel would and even though it is called stainless steel, it is not entirely stainless, because in low-oxygen, high salinity environments it is able to be stained. The main difference between stainless steel and general carbon steel is the amount of chromium present. Due to the amount of chromium that stainless steel contains, the stainless steel will form a chromium oxide film which will help prevent corrosion as it blocks the oxygen fusing to the surface of the…
