Balanced equation

Balance the chemical equation algebraically: H_2SO_4 + Al + KClO ⟶ H_2O + KCl + Al_2(SO_4)_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2SO_4 + c_2 Al + c_3 KClO ⟶ c_4 H_2O + c_5 KCl + c_6 Al_2(SO_4)_3 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S, Al, K and Cl: H: | 2 c_1 = 2 c_4 O: | 4 c_1 + c_3 = c_4 + 12 c_6 S: | c_1 = 3 c_6 Al: | c_2 = 2 c_6 K: | c_3 = c_5 Cl: | c_3 = c_5 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_6 = 1 and solve the system of equations for the remaining coefficients: c_1 = 3 c_2 = 2 c_3 = 3 c_4 = 3 c_5 = 3 c_6 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 3 H_2SO_4 + 2 Al + 3 KClO ⟶ 3 H_2O + 3 KCl + Al_2(SO_4)_3
