Fill in the coefficients that was will balance the following reaction SnSO4 + KBr SnBr2 K2SO4

Juliette [100K]

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:

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

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

Sn - 1

$S O_{4}$ - 1

K - 1

Br - 1

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

Sn - 1

$S O_{4}$ - 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.

$\Sn S O_{4}+2 K B r \rightarrow S n B r_{2}+K_{2} S O_{4}$

Hence,

$a_{0} - 1\\a_{1} - 2\\a_{2} - 1\\a_{3} - 1$
