Balanced equation

Balance the chemical equation algebraically: HNO_3 + FeSO_4 ⟶ H_2O + H_2SO_4 + NO + Fe(NO_3)_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 HNO_3 + c_2 FeSO_4 ⟶ c_3 H_2O + c_4 H_2SO_4 + c_5 NO + c_6 Fe(NO_3)_3 Set the number of atoms in the reactants equal to the number of atoms in the products for H, N, O, Fe and S: H: | c_1 = 2 c_3 + 2 c_4 N: | c_1 = c_5 + 3 c_6 O: | 3 c_1 + 4 c_2 = c_3 + 4 c_4 + c_5 + 9 c_6 Fe: | c_2 = c_6 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_5 = 1 and solve the system of equations for the remaining coefficients: c_1 = 10 c_2 = 3 c_3 = 2 c_4 = 3 c_5 = 1 c_6 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 10 HNO_3 + 3 FeSO_4 ⟶ 2 H_2O + 3 H_2SO_4 + NO + 3 Fe(NO_3)_3
