that Affect the Rate of a Reaction BACKGROUND: Chemical reactions occur at different rates. In this experiment I will consider some of the key factors that influence the rate of a reaction: * nature of reactants - particle size * temperature * catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However‚ in order for the

Calorimeter Determination of Reaction Enthalpy 9/11/2014 Introduction: A chemical reaction often indicated by a transfer of energy measured in heat. By measuring this heat transfer in a constant pressurized environment‚ the enthalpy of the reaction can be used to infer certain information about a specific reactions reactants and products. The transfer of heat from outside sources in would be described as an endothermic reaction. Contrary‚ when a reaction releases heat out to its surroundings

started looking into other products that I use fairly regularly‚ like Febreze. Apparently Febreze contains quite a few ingredients that have been found to be toxic to humans. Some of the harmful ingredients found in Febreze are butylated hydroxytoluene (BHT)‚ “fragrance‚” and methyl pyrrolidone. These‚ as well as the many other ingredients in Febreze‚ are found to be immunotoxins and can

Ethical Lens Inventory Keith A. Hovey US/101 May 19‚ 2013 Karen Alston Ethical Lens Inventory My ethical lens inventory suggests that I have a rounded sense of things. It was a pretty accurate assessment of how I see the world‚ and of how I make my decisions. I really do try to see all sides of anything so that I can determine a sensible outcome. I do attempt to remain ethical at all times as I move about in the world‚ but it is right in one other case. I do have a difficult time

Microprocessors operate on numbers and symbols represented in the binary numeral system. The advent of low-cost computers on integrated circuits has transformed modern society. General-purpose microprocessors in personal computers are used for computation‚ text editing‚ multimedia display‚ and communication over the Internet. Many more

So everyone should have an ambition in life but simply having it is not enough. Whatever be the ambition‚ it must be backed up by contain efforts to achieve it. If a person sets an ambition before him‚ but does or to achieve it‚ his ambition is no more than an idle dream or a pious resole Different persons have different ambitions the nature of ambition from man to man‚ depending upon his family background‚ upbringing‚ s status and economic condition‚ etc. Thus‚ some peoples only ambition in is to

was synthesis by reacting concentrated hydrochloric acid using nucleophilic substitution sn1. In the substitution reaction the Hydrogen in HCl protonated the alcohol group in t-pentyl alcohol and turned it to a good leaving group (H2O). a tertiary carbon cation was formed. a nucleophilic attach of the negative Cl- attacked the carbon cation forming t-pentyl chloride [7]. As the reaction proceeded‚ extraction and distillation techniques were used to get a pure product of t-pentyl chloride. The percent

Symbolization Found in The Pearl “This pearl has become my soul... If I give it up‚ I shall lose my soul” (Steinbeck chapter 5). The book The Pearl was written by John Steinbeck in 1947. The setting of the book takes place in a small town in Mexico somewhere during the late 1800’s. The main characters are Kino‚ a lowly pearl hunter‚ Juana his faithful‚ thoughtful wife and Coyotito‚ the family’s infant child.
