EXPERIMENT I Photoreduction of Benzophenone Introduction The study of chemical reactions‚ isomerizations and physical behavior that may occur under the influence of visible and/or ultraviolet light is called Photochemistry. The fundamental principles for understanding photochemical transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for

must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine. Usually iodine has a orange-yellow color‚ but iodine and starch react to produce a dark blueblack color‚ so iodine may be used as an indicator to show the rate at which starch is broken down.1 This occurs when polyiodide chains are formed from starch and iodine. However‚ as starch is hydrolyzed into smaller

Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid. What I already know Magnesium reacts with most dilute acids to give a magnesium salt and hydrogen. For

This lab report is not perfect‚ but can serve as a guide in understanding how to write one! Introduction Insulin‚ an amino-acid based protein‚ helps make up a larger polypeptide chain‚ proinsulin‚ which is located within the beta cells of the pancreas. Enzymes release the insulin from the larger proinsulin chain just before it is secreted from the beta cells. Insulin’s main function is to lower blood glucose levels by speeding up the membrane transport of glucose from the blood and into
