Step-by-step explanation:

A chemical reaction equation that has equal number of atoms on both reactant and product side is known as a balanced equation.

For example,
SnSO_(4) + KBr \rightarrow SnBr_(2) + K_(2)SO_(4)

Number of atoms present on reactant side are as follows.

Sn = 1


SO_(4) = 1

K = 1

Br = 1

Number of atoms on product side are as follows.

Sn = 1


SO_(4) = 1

K = 2

Br = 2

Therefore, to balance this chemical equation multiply KBr by 2 on reactant side. So, the balanced chemical equation is as follows.


SnSO_(4) + 2KBr \rightarrow SnBr_(2) + K_(2)SO_(4)

Hence,
a_(0) = 1,
a_(1) = 2,
a_(2) = 1, and
a_(3) = 1.

It is important to remember that when you balance reactions that number of atoms for each substances is the same in the reactants and the products side. Therefore, the balanced chemical reaction is

SnSO4 + 2KBr → SnBr2 + K2SO4

The coefficiens are 1:2:1:1. Hope this answers the question. Have a nice day.
