Introduction To Chemical Reactions and Equation
CHEMICAL REACTION A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products . For example: Rusting of iron, the setting of milk into curd, digestion of food, respiration, etc . A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae , wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side with a plus sign between the entities in both the reactants and the products. SOME EXAMPLES OF CHEMICAL REACTION Combustion. Oxidation (rusting) Decomposition or fermentation. Cooking an egg. Photosynthesis. Reacting acids and bases together. Chemical batteries. Digestion.
