Balanced equation

Balance the chemical equation algebraically: HOCl + MnS ⟶ HCl + MnSO_4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 HOCl + c_2 MnS ⟶ c_3 HCl + c_4 MnSO_4 Set the number of atoms in the reactants equal to the number of atoms in the products for Cl, H, O, Mn and S: Cl: | c_1 = c_3 H: | c_1 = c_3 O: | c_1 = 4 c_4 Mn: | c_2 = c_4 S: | c_2 = c_4 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 4 c_2 = 1 c_3 = 4 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 4 HOCl + MnS ⟶ 4 HCl + MnSO_4
