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.
