Answer:

Step-by-step explanation:
An equation that constitute equal number of atoms on both reactant and product side is known as a balanced chemical equation.
For example,

Number of atoms on reactant side are as follows.
C = 1
Cl = 4
Number of atoms on product side are as follows.
C = 1
Cl = 2
To balance this equation we will multiply
by 2 on product side.
Hence, the balanced chemical equation will be as follows.
