Balanced equation

Balance the chemical equation algebraically: HCl + HNO_3 + Au ⟶ H_2O + NO_2 + HAuCl_4·xH_2O Add stoichiometric coefficients, c_i, to the reactants and products: c_1 HCl + c_2 HNO_3 + c_3 Au ⟶ c_4 H_2O + c_5 NO_2 + c_6 HAuCl_4·xH_2O Set the number of atoms in the reactants equal to the number of atoms in the products for Cl, H, N, O and Au: Cl: | c_1 = 4 c_6 H: | c_1 + c_2 = 2 c_4 + c_6 N: | c_2 = c_5 O: | 3 c_2 = c_4 + 2 c_5 Au: | c_3 = c_6 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_3 = 1 and solve the system of equations for the remaining coefficients: c_1 = 4 c_2 = 3 c_3 = 1 c_4 = 3 c_5 = 3 c_6 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 4 HCl + 3 HNO_3 + Au ⟶ 3 H_2O + 3 NO_2 + HAuCl_4·xH_2O
