Whenever a chemical change occurs, we can say that a chemical reaction has taken place. In a chemical reaction, a new substance is formed which is completely different in properties from the original substance. The transformation of chemical substance into another chemical substance is known as Chemical Reaction..
Representation of chemical reaction using symbols and formulae of the substances is called Chemical Equation. Chemical equations were first formulated by the French chemist Jean Beguin in the year 1615.

A chemical equation can be divided into two types:
(a) Balanced Chemical Equation
(b) Unbalanced Chemical Equation

Do you know Chemical reactions are of 5 types:
Combination Reaction
Decomposition Reaction
--- Decomposition reaction also divided into 3 types these are
----------Thermal Decomposition,
----------Electrolytic Decomposition,
----------Photolysis or Photo Decomposition Reaction
Displacement Reaction
Double Displacement Reaction
Oxidation and Reduction Reactions
