Rate Of Reaction Bunsen Burner
1,230 wordsInvestigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: &# 61656; Increasing the concentration. (See the lock and key theory. ) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. &# 61656; The surface area, the bigger t...

Liquid Nitrogen Surface Area
1,858 wordsIntroduction Background and Theory. Experimental Procedure. Results and Discussion Conclusions and Recommendations Nomenclature... References B. Equipment Diagram... The hydrogenolysis of ethane on a nickel on kieselguhr catalyst has only been conducted using a cylindrical pellet shaped catalyst of unknown surface area. We used a powdered version of this catalyst and compared its performance with that of the pellet catalyst. This comparison was conducted using one gram of catalyst in each reacto...

Catalytic Converter Carbon Monoxide
705 wordsIntroduction There are millions of cars on the road in the United States, and each one is a source of air pollution. Especially in large cities, the amount of pollution cars produce everyday is a lot. To solve those problems, many laws have been enacted restricting the amount of pollution that cars can produce. To make their cars as pollution-free as possible, automakers have made many refinements to car engines and fuel systems and have developed the catalytic converter. The catalytic converter...

Concentration And Reaction Rate
1,776 wordster> How concentration affects reaction rate. The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from being transparent to translucent to opaque. The sulphur is formed as a solid but not in the usual precipitation way. Na 2 + S 2 + 2 HCL 2 NaCl+...

People Of Color Sexual Harassment
2,442 wordsManaging Diversity in the Workplace The issues of gender and diversity in organizations are inextricably linked. Researchers, practitioners, and even laypersons have known for decades that women and racial minorities constitute a growing percentage of the labor force. More importantly, this growth exists at all levels of the organizational hierarchy. That said, however, groups that represent a statistical or social minority, or both continue to face challenges in U. S. organizations. A variety o...

1,372 wordsCatalysts &# 038; Fine Particle In Industry Catalyst: Catalysis, alteration of the speed of a chemical reaction, through the presence of an additional substance, known as a catalyst, that remains chemically unchanged by the reaction. Enzymes, which are among the most powerful catalysts, play an essential role in living organisms, where they accelerate reactions that otherwise would require temperatures that would destroy most of the organic matter. A catalyst in a solution with-or in the same ph...

Othello And Desdemona Act 3 Scene 3
1,319 wordsDoes Iago Cause The Tragedy Of Othello Does Iago Cause The Tragedy Of Othello And Desdemona, Or Is He Merely The Catalyst The Shakespeare Tragedy, Othello, was written and set during the early 17 th century Venice rule. ? The play is set in Cyprus and Venice. ? There are many arguments whether Iago causes the tragedy towards the end of the play, or whether he is merely the catalyst. To many, Iago is the most evil character in the play. ? He is blamed for the tragedy of Othello and Desdemona. ? H...

Carbon Monoxide Carbon Dioxide
4,029 wordsThe Exhaust Systems Exhaust Systems The exhaust system on a car is the most important device to keep our environment clean. Many exhaust emissions from the engine such as water, oxygen, nitrogen, and carbon dioxide, are of little concern. Others, such as hydrocarbons (HC), oxides of nitrogen (NO), and carbon monoxide (CO), can cause environmental and health problems if not controlled. Hydrocarbon emissions react with sunlight, which cause photochemical smog. The exhaust system controls these the...
