The coefficients are 1 : 2 : 1 : 1

Explanation:

To be a balanced equation, the chemical equation should have has equal number of atoms on both reactant and product side.

Given chemical equation:

        [tex]a_{0} {SnSO}_{4}+a_{1} K B r \rightarrow a_{2} {SnBr}_{2}+a_{3} K_{2} S O_{4}[/tex]

Now, calculate the number of atoms present in reactant side:

Sn - 1

[tex]S O_{4}[/tex] - 1

K - 1

Br - 1

Then, calculate the number of atoms present in product side:

Sn - 1

[tex]S O_{4}[/tex] - 1

K - 2

Br - 2

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

       [tex]\Sn S O_{4}+2 K B r \rightarrow S n B r_{2}+K_{2} S O_{4}[/tex]

Hence,

[tex]a_{0} - 1\\a_{1} - 2\\a_{2} - 1\\a_{3} - 1[/tex]
