Chemistry Exam Study Sheet Organic Chemistry • Study of compounds to which carbon is the principal element. • Carbon is special because it has 4 bonds. Functional Groups • Organic substances are organized into organic families. • Organic Families – group of organic compounds with common structural features. o Each family has a recognizable physical property and a specific structural arrangement. o Each combination is referred to as a functional group. o Even

essential for our bodies. In the body these fatty acids are modified to make eicosanoids. These are the signaling molecules that have complex control over growth‚ inflammation‚ immunity‚ maintaining healthy skin‚ to name just a few. They are made by oxidation of twenty carbon chain fatty acids. The amount of these fatty acids in the diet will affect the body’s ability to make these eicosanoids‚ therefore having a direct effect on all of the functions the eicosanoids are responsible for‚ including growth

commercially available formalin has 10 to 12% methanol with a few impurities like aluminum and copper. Almost 21 million tonnes of formaldehyde is produced annually all around the world. Synthesis of Formaldehyde Formaldehyde is produced by catalytic oxidation of methanol. A mixture of molybdenum and iron or silver is used as a catalyst in such a reaction. But a more commonly used process is FORMAX. In this process‚ methanol and oxygen react at temperatures more than 250ºC in presence of vanadium to produce

Fig. 7A displays the amperometric response of Ag/ZSM-5/CPE with successive injection of OA into a stirred solution of 0.1 M NaHPO4 pH= 2 recorded at the potential of 0.73 V vs. Ag|AgCl in the concentration ranges from 16 μM to 4.0 mM. It can be seen that the aerometric current increases clearly after each injection of OA. Fabricated sensor displays the rapid response towards change in the concentration of OA which reaches a steady state within 2 s by applying the potential of 0.73 V to Ag/ZSM-5/CPE

A Seminar Report on “CATALYTIC CONVERTER” PREFACE Catalytic converter is most effective device which converts harmful gases due to engine exhaust into eco-friendly gases. In this report‚ we have tried to bring into focus imports of reducing air pollution and why catalytic converter is necessary in automobile. We also tried to bring advance technology found out now a day for reducing air pollution. By best effort‚ we try to focus necessity of subject. We hope our report is one
