Balanced equation

Balance the chemical equation algebraically: ZnCl_2 + LiOH ⟶ Zn(OH)_2 + LiCl Add stoichiometric coefficients, c_i, to the reactants and products: c_1 ZnCl_2 + c_2 LiOH ⟶ c_3 Zn(OH)_2 + c_4 LiCl Set the number of atoms in the reactants equal to the number of atoms in the products for Cl, Zn, H, Li and O: Cl: | 2 c_1 = c_4 Zn: | c_1 = c_3 H: | c_2 = 2 c_3 Li: | c_2 = c_4 O: | c_2 = 2 c_3 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 = 2 c_3 = 1 c_4 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | ZnCl_2 + 2 LiOH ⟶ Zn(OH)_2 + 2 LiCl
