but explosive combustion‚ such as the ignition of fuel‚ can take as little as fractions of a second to complete. Dealing closely with reaction rates is collision theory. First proposed in 1916‚ collision theory describes qualitatively how and why chemical reactions occur‚ and how the rate of reactions differs from reaction to reaction. It theorises that‚ for a reaction to occur‚ the reactant particles must collide‚ but only a fraction of the total collisions cause actual transformations of reactant

Chemical Reactions The idea of chemical reactions was investigated about two hundred and fifty years ago‚ when a man named Antoine Laurent Lavoisier wanted to know about the importance of chemical changes. Also‚ in the 19th century‚ John Dalton made the atomic theory. Dalton said that bonding atoms together makes new substances‚ which is a chemical reaction (History of chemical reactions). The definition of chemical reaction is‚ “the processes in which substances undergo chemical changes‚ which

OVERVIEW The Dow Chemical Company was a leader company in science and technology‚ offering plastic and agriculture products in 2002. However‚ from 1995‚ Dow Chemical Company had ever lost its profit for several years especially in 1998. Dow Chemical Company tried to stop the decreasing so that it launched an initiative ‘E-epoxy.com venture’ in 2000. The purpose of this project was earning more small customers and spot market customers to increase the market shares. STRENGTH 1. Epoxy was a specialty

In this lab‚ theoretical chemical equations of ionic compounds were balanced by the group to determine ratios of reactants and products. The products were determined by the group through switching the cation with their anion partner. Using this information‚ it was determined by the group‚ whether the reaction should result in a solid‚ gas‚ or water based on theoretical solubility. Then several experiments testing the reaction of these ionic compounds were performed by the partners. Two ionic compounds
