Balanced equation

Balance the chemical equation algebraically: SO_2 + NaHCO_3 ⟶ CO_2 + NaHSO_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 SO_2 + c_2 NaHCO_3 ⟶ c_3 CO_2 + c_4 NaHSO_3 Set the number of atoms in the reactants equal to the number of atoms in the products for O, S, C, H and Na: O: | 2 c_1 + 3 c_2 = 2 c_3 + 3 c_4 S: | c_1 = c_4 C: | c_2 = c_3 H: | c_2 = c_4 Na: | 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 1 c_3 = 1 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | SO_2 + NaHCO_3 ⟶ CO_2 + NaHSO_3
