    The balanced equation is given below:

    SO4^2 - (aq) + Sn^2 + (aq) + 4H^ + (aq) → H2SO3 (aq) + Sn^4 + (aq) + H2O (l)

    The coefficients of the reactants are: 1, 1, 4

    The coefficients of the products are: 1, 1, 1

    Explanation:

    Step 1:

    The equation for the reaction. This is given below:

    SO4^2 - (aq) + Sn^2 + (aq) + - --→ H2SO3 (aq) + Sn^4 + (aq) + - --

    Step 2:

    Inclusion of H + and H2O into the equation. This is illustrated below:

    SO4^2 - (aq) + Sn^2 + (aq) + H^ + (aq) → H2SO3 (aq) + Sn^4 + (aq) + H2O (l)

    Step 3:

    Balancing the equation.

    SO4^2 - (aq) + Sn^2 + (aq) + H^ + (aq) → H2SO3 (aq) + Sn^4 + (aq) + H2O (l)

    The above equation can be balanced as follow:

    There are total 4 atoms of H on the right side and 1 atom on the left side. It can be balance by putting 4 in front of H^ + as shown below:

    SO4^2 - (aq) + Sn^2 + (aq) + 4H^ + (aq) → H2SO3 (aq) + Sn^4 + (aq) + H2O (l)

    Now the equation is balanced.

    The coefficients of the reactants are: 1, 1, 4

    The coefficients of the products are: 1, 1, 1
