Step-by-step explanation:
A balanced equation is defined as the equation which contains same number of atoms on both reactant and product side.
For example,

Number of atoms on reactant side are as follows.
Number of atoms on product side are as follows.
So, in order to balance this equation we will multiply
by 2 on the product side and multiply
by 3 on the reactant side.
Hence, the balanced reaction equation will be as follows.
