Balanced equation

Balance the chemical equation algebraically: H_2SO_4 + Ca(OH)_2 ⟶ H_2O + CaOH2SO4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2SO_4 + c_2 Ca(OH)_2 ⟶ c_3 H_2O + c_4 CaOH2SO4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S and Ca: H: | 2 c_1 + 2 c_2 = 2 c_3 + 2 c_4 O: | 4 c_1 + 2 c_2 = c_3 + 5 c_4 S: | c_1 = c_4 Ca: | 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: | | H_2SO_4 + Ca(OH)_2 ⟶ H_2O + CaOH2SO4
