HNO3 + Fe3O4 = H2O + NO + Fe(NO3)3

Input interpretation

nitric acid + iron(II, III) oxide ⟶ water + nitric oxide + ferric nitrate
nitric acid + iron(II, III) oxide ⟶ water + nitric oxide + ferric nitrate

Balanced equation

Balance the chemical equation algebraically:  + ⟶ + +  Add stoichiometric coefficients, c_i, to the reactants and products: c_1 + c_2 ⟶ c_3 + c_4 + c_5  Set the number of atoms in the reactants equal to the number of atoms in the products for H, N, O and Fe: H: | c_1 = 2 c_3 N: | c_1 = c_4 + 3 c_5 O: | 3 c_1 + 4 c_2 = c_3 + c_4 + 9 c_5 Fe: | 3 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 = 28 c_2 = 3 c_3 = 14 c_4 = 1 c_5 = 9 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 28 + 3 ⟶ 14 + + 9
