heat gained by the solution was 2508 J whereas the heat gained by the calorimeter was 173.4 J. Therefore the number of joules released per mole of water formed was 47.6. Kj/mol. In the heat of neutralization of HC2H3O2-NaOH‚ the heat gained by the solution was 2549.8 J‚ and the heat gained by the calorimeter was 176.3 J. The number of joules released per mole of water formed = 47.4 kJ/mol. The total number of joules released in reaction B (2384.6 J) was more than those released in reaction B (2372

Limit The Use of Technology Over the past several years’ technology has advanced significantly. Nowadays most everything we use is done by some form of technology. Several years ago‚ we didn’t even have cellphones or the Internet‚ now we have cellphones that can access the Internet. This generation has become so dependent with technology that it is actually beginning to harm most us‚ not help us. So this leads us to believe one should limit his or her use of technology because it could cause addiction

Identification and Production of Materials ================================ Ethene‚ Polymers and Ethanol ================================ Catalytic Cracking Oil refineries need to balance their outputs of various products (petrol‚ diesel‚ fuel oil‚ etc.) to match the demands of the marketplace. Catalytic cracking is the process in which high molecular weight (high boiling point) fractions from crude oil are broken into lower molecular weight (lower boiling point) substances in order to increase

Factors Limiting Photosynthesis The rate of photosynthesis increases with increasing light intensity. But too much light intensity can slow down the rate of photosynthesis because the light damages chloroplasts in the leaf. The higher the temperature the greater the rate of photosynthesis as photosynthesis is a chemical reaction and chemical reactions increase with temperature. But at temperatures above 40 C the rate slows down because the enzymes involved are destroyed

Epoxidation Reactions Lab Report 2 Abstract An oxygen atom is transferred from a peroxy acid to the carbon=carbon double bond thus forming an epoxide. Scheme 1. Oxone Epoxidation. Scheme 2. mCPBA Epoxidation. The percent yield for the Oxone epoxidation reaction was 65% yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic

3 February 17‚ 2013 The article‚ “The Sharpe Ratio and the Information Ratio”‚ by Deborah Kidd is about the original risk-adjusted performance measure and they are Sharpe ratio and the Information Ratio. William Sharpe designed the first performance metric to insolate excess return per unit of total risk taken. The Sharpe ratio shows whether a portfolio ’s returns are due to smart investment decisions or a result of excess risk. The Sharpe ratio measure dividends average portfolio excess return
