Brittany Martin 2/13/2014 Diels Alder reaction of anthracene and Maleic anhydride Reaction Scheme: Figure one shows the reaction scheme for Diels Alder reaction of anthracene and maleic anhydride Theory/Background: The Diels-Alder reaction was created in 1928 by two German chemists Otto Diels and Kurt Alder (Wade‚ Jr.‚ 2013). This reaction is best used for making six membered rings with different functional groups. The reaction is called a 4+2 cycloaddition because a ring is formed

Trivia and other Information: The best way to prevent lung cancer is to avoid smoking. If you currently smoke‚ ask your health care provider to assist you in finding resources to help you quit smoking. It is also important to try to avoid second-hand tobacco smoke‚ radon‚ asbestos and pollution‚ which can increase a person’s risk of developing lung cancer. Controlling other lung diseases‚ such as tuberculosis can help prevent lung cancer‚ since there is evidence that lung cancer tends to develop

Iodine-Clock Reaction: S2O82−(aq) + 2 I−(aq) → I2(aq) + 2 SO42−(aq) To measure the rate of this reaction we must measure the rate of concentration change of one of the reactants or products. Here‚ it is convenient to carry out a clock reaction involving the product I2. To do this‚ you will include (to the reacting S2O82− and I−) i) a small (but accurately known) amount of sodium thiosulfate‚ Na2S2O3‚ and ii) some starch indicator. The added Na2S2O3 does not interfere with the rate of above reaction‚ but

BSBHRM402A: Recruit‚ select and induct staff Assessment activities. Assessment activity 1 1. How can an organisation identify the need to make an appointment An organisation can identify the need to make an appointment through the use of “staffing table”‚ it shows jobs within the organisation‚ their occupants‚ reporting relationships and lines of authority 2. What impact does recruiting have on an organisation’s resources Some impacts of recruiting can be positive or negative. The process

The Rate of a Reaction The area of chemistry that deals with the rate or speed of chemical reactions is known a chemical kinetics. The word “kinetic” is derived from the Greek name kinitikos that means movement or motion. In the present context‚ the kinetic means the reaction rate or rate of a reaction that is defined as the change in concentration of a reactant or a product with time (M/s). Chemical reaction can be represented by the following general equation. Reactants Products It is very important

IODINE-CLOCK REACTION DATE SUBMITTED: 14 DECEMBER 2012 DATE PERFORMED: 7 DECEMBER 2012 ABSTRACT Chemical kinetics involving reaction rates and mechanisms is an essential part of our daily life in the modern world. It helps us understand whether particular reactions are favorable and how to save time or prolong time during each reaction. Experiment demonstrated the how concentration‚ temperature and presence of a catalyst can change the rate of a reaction. 5 runs of dilution and reaction were made
