Balanced equation

Balance the chemical equation algebraically: HNO_3 + HOC(CH_3)(CH_2CO_2H)_2 ⟶ H_2O + CO_2 + N_2O_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 HNO_3 + c_2 HOC(CH_3)(CH_2CO_2H)_2 ⟶ c_3 H_2O + c_4 CO_2 + c_5 N_2O_3 Set the number of atoms in the reactants equal to the number of atoms in the products for H, N, O and C: H: | c_1 + 10 c_2 = 2 c_3 N: | c_1 = 2 c_5 O: | 3 c_1 + 5 c_2 = c_3 + 2 c_4 + 3 c_5 C: | 6 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 = 12 c_2 = 1 c_3 = 11 c_4 = 6 c_5 = 6 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 12 HNO_3 + HOC(CH_3)(CH_2CO_2H)_2 ⟶ 11 H_2O + 6 CO_2 + 6 N_2O_3
