Balanced equation

Balance the chemical equation algebraically: Na_2CO_3 + AlCl_3 ⟶ NaCl + Al2(CO3)3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 Na_2CO_3 + c_2 AlCl_3 ⟶ c_3 NaCl + c_4 Al2(CO3)3 Set the number of atoms in the reactants equal to the number of atoms in the products for C, Na, O, Al and Cl: C: | c_1 = 3 c_4 Na: | 2 c_1 = c_3 O: | 3 c_1 = 9 c_4 Al: | c_2 = 2 c_4 Cl: | 3 c_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_4 = 1 and solve the system of equations for the remaining coefficients: c_1 = 3 c_2 = 2 c_3 = 6 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 3 Na_2CO_3 + 2 AlCl_3 ⟶ 6 NaCl + Al2(CO3)3
