Balanced equation

Balance the chemical equation algebraically: H_2SO_4 + Mn ⟶ H_2O + H_2S + MnSO_4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2SO_4 + c_2 Mn ⟶ c_3 H_2O + c_4 H_2S + c_5 MnSO_4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S and Mn: H: | 2 c_1 = 2 c_3 + 2 c_4 O: | 4 c_1 = c_3 + 4 c_5 S: | c_1 = c_4 + c_5 Mn: | c_2 = c_5 Since the coefficients are relative quantities and underdetermined, choose a coefficient to set arbitrarily. To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c_4 = 1 and solve the system of equations for the remaining coefficients: c_1 = 5 c_2 = 4 c_3 = 4 c_4 = 1 c_5 = 4 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 5 H_2SO_4 + 4 Mn ⟶ 4 H_2O + H_2S + 4 MnSO_4
