B. `5BiO_3^(-) + 22H^(+) + Mn^(2+) to 5Bi^(3+) + 7H_2O + MnO_4^-`
C. `6BiO_3^(-) + 12H^(+) + 3Mn^(2+) to 6Bi^(3+) + 6H_2O + 3MnO_4^-`
D. `2BiO_3^(-) + 4H^(+) + Mn^(2+) to 2Bi^(3+) + 6H_2O + 3MnO_4^-`

Answer

A

Explanation

The equation is said to be balanced, if number of atoms and charge on the reactant and product sides are equal. In option
,
Number of atoms of reactant side = number of atoms in product side and charge on reactant slde = charge on product side
