Affecting Rates of Chemical Reactions Prepared By: Kelly Gunter For: Ms. Brohman Course: SCH-4U Introduction The main purpose of this lab was to investigate how temperature‚ concentration‚ the addition of catalysts‚ and the substitution of a more reactive reactant‚ can affect the reaction. The collision theory explains that in order for a reaction to occur‚ reacting particles must collide with one another. An effective collision makes reactants result in a reaction and for to

AbstractThe rates of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the resulting metal solutions are tested and the products of the reaction between calcium and water is discovered. The tested elements are sodium‚ lithium‚ potassium and calcium and each of them were placed in a beaker filled with water. The resulting solutions pH levels were tested with litmus paper. There were more steps for caclium because it is the only Alkaline Earth metal. For

Professor English 102 Critical Evaluation Essay: A Petition to the President of the United States The atomic bombs that were dropped on Japan in 1945 were not seen as a logical reaction to the war by everyone. Leo Szilard was a Hungarian physicist that was the first to conceive of the mechanics of the atomic bomb‚ and how it worked. He was fighting the use of these bombs on Japan‚ and trying to urge the President to reconsider the idea. Although he lost the argument over

I. Introduction 1. The revised policy of UNDP for evaluation was approved in 2011. The purpose of the policy is to establish a common institutional basis for the UNDP evaluation function. The policy seeks to increase transparency‚ coherence and efficiency in generating and using evaluative knowledge for organizational learning and effective management for results‚ and to support accountability. The policy also applies to UNDP and its associated funds and programmes – the United Nations Capital Development

Evaluation of Voluntourism A trend has started in the recent years‚ where people participate in organizations that commonly claim to be helping developing countries. This trend is fuelled by the gap year phenomenon‚ which is defined as “a period of time between 3 and 24 months taken out of education or a work career.” (Jones‚ 2004) With enthusiasm of “making a difference”‚ more and more people choose voluntourism‚ combination of tourism and volunteer projects‚ as their gap year holiday option.
