Balanced equation

Balance the chemical equation algebraically: Ca(OH)_2 + H_2SO_3 ⟶ H_2O + CaSO3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 Ca(OH)_2 + c_2 H_2SO_3 ⟶ c_3 H_2O + c_4 CaSO3 Set the number of atoms in the reactants equal to the number of atoms in the products for Ca, H, O and S: Ca: | c_1 = c_4 H: | 2 c_1 + 2 c_2 = 2 c_3 O: | 2 c_1 + 3 c_2 = c_3 + 3 c_4 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 1 c_3 = 2 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | Ca(OH)_2 + H_2SO_3 ⟶ 2 H_2O + CaSO3
