Balanced equation

Balance the chemical equation algebraically: HCl + Al(OH)_3 ⟶ H_2O + AlOHCl2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 HCl + c_2 Al(OH)_3 ⟶ c_3 H_2O + c_4 AlOHCl2 Set the number of atoms in the reactants equal to the number of atoms in the products for Cl, H, Al and O: Cl: | c_1 = 2 c_4 H: | c_1 + 3 c_2 = 2 c_3 + c_4 Al: | c_2 = c_4 O: | 3 c_2 = c_3 + 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 = 2 c_2 = 1 c_3 = 2 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 2 HCl + Al(OH)_3 ⟶ 2 H_2O + AlOHCl2
