Balanced equation

Balance the chemical equation algebraically: H_2SO_4 + FeO ⟶ H_2O + S + Fe_2(SO_4)_3·xH_2O Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2SO_4 + c_2 FeO ⟶ c_3 H_2O + c_4 S + c_5 Fe_2(SO_4)_3·xH_2O Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S and Fe: H: | 2 c_1 = 2 c_3 O: | 4 c_1 + c_2 = c_3 + 12 c_5 S: | c_1 = c_4 + 3 c_5 Fe: | c_2 = 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 = 10 c_2 = 6 c_3 = 10 c_4 = 1 c_5 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 10 H_2SO_4 + 6 FeO ⟶ 10 H_2O + S + 3 Fe_2(SO_4)_3·xH_2O
