Feeney Biology 9 October 16‚ 2012 Identifying Organic Compounds Objective: To use indicators to test for the presence of organic compounds in certain substances. Theory: Major types of organic compounds in some common foods are Lipids‚ Carbohydrates‚ and Proteins. An indicator is a chemical compound that changes color and structure when exposed to certain conditions and is therefore useful for chemical tests. The purpose of using distilled water as one of the substances in the test is that

creation of one of the most destructive weapons known to humanity occurred within the United States. This weapon‚ known as “the atomic bomb‚” was used on the two Japanese cities: Hiroshima and Nagasaki‚ resulting in a death toll unprecedented by any military weapon used before and an immediate‚ unconditional surrender. Some historians believe President Truman decided to drop the atomic bomb in order to intimidate the Soviet Union whereas others believe it was a strictly military measure designed to force

PURIFICATION OF ORGANIC COMPOUNDS AIMS: To isolate organic‚ inorganic and component from a given sample. To become acquainted with various separation methods. To examine the solubility behavior of the various compounds in a mixture using different solvents. INTRODUCTION A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some

The Atomic Bomb on Hiroshima and Nagasaki in 1945 The Atomic bomb on Hiroshima and Nagasaki in 1945 will always be remembered. On August 6‚ 1945‚ the city of Hiroshima was the target of the first Atomic Bomb. Three days later the second Atomic Bomb was dropped over the city of Nagasaki The decision to use the Atomic Bomb came after much thought by President Truman. The Chief of the Manhattan Project informed the president on the destructive force that came with the use of the Atomic Bomb

I. Abstract The common organic compounds provide us with nutrients are sugars and starches‚ carbohydrates‚ proteins‚ and lipids. In this lab‚ qualitative tests are performed to identify the presence of organic compounds in food using indicators‚ chemical substances that react in a certain way when a particular substance is present. We put one indicator into the each test tube containing different solutions at a time to see what organic compound is present. The color change in the indicator tells

carbonyl compounds is useful in reactions because nitriles are versatile functional groups1. Not only are they versatile functional groups but they serve as precursors in several transformations. The cyano-group is found in many bioactive molecules and plays a role in hydrogen bonding to certain biological receptors.4 Nitriles are carboxylic acid derivatives because they can easily be converted to carboxylic acid under either basic or acidic conditions. Piperonal is an aromatic compound that is present

Link reaction The link reaction takes place in the mitochondrial matrix and its main function is to turn the pyruvate into acetate for the kerb cycle. During the link reaction the pyruvate molecule undergoes decarboxylation and dehydrogenation‚ the enzymes pyruvate decarboxylase and pyruvate dehydrogenase remove the carboxyl group (which becomes a carbon dioxide molecule) and removes the hydrogen atoms from the pyruvate molecule. The coenzyme NAD accepts the two hydrogen atoms and becomes reduced

A rope is a very strong symbolisation of Piggy because they both hold things together. This representation is true because people use rope to tie or hold things together much like Piggy does during the story. A quote from the text to show this is “The first thing we ought to have made was shelters down there by the beach” (Golding 35). In addition piggy exemplifies a rope because he supports the group. A key way Piggy supports the group is taking care of the little ones. In conclusion Piggy symbolises
