Properties of Chemical Reactions Ms. Whitty‚ Science 10 Fiona Adams‚ November 1st‚ 2012 Introduction Chemical reactions are a part of our daily lives‚ from rusting metal to making bread to leaves changing colour in the fall. A chemical reaction is the process that occurs when two or more substances combine to produce a chemical change. When a chemical reaction takes place‚ the change is indicated by one or more qualitative properties. The colour or odor could change‚ gas could be produced

Introduction: Chemical equilibrium is when the concentrations of the reactants and products have reached a state where reactions occurring in one direction are at the same rate of reactions occurring in the opposite direction. This process‚ called dynamic equilibrium‚ is the main subject of Le Chatelier’s Principle. Le Chatelier pointed out that if a system at equilibrium is subjected to a stress that momentarily causes the system to be not in equilibrium‚ a spontaneous change will occur to

Three factors influence the Industrial revolution‚ these factors include :a population boom: a canal boom: and policies of the government of parliament. The revolution first occurred in Britain and later spread throughout the world. Cotton also had a prevalent influence on the revolution‚ these influences are demonstrated in the Cottage Industries. The Industrial revolution created a major energy crisis which was solved by James Watt. During the revolution the first locomotive (the Rocket) was invented
