Balanced equation

Balance the chemical equation algebraically: Na_2SO_4 + CaCl_2 ⟶ NaCl + CaSO_4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 Na_2SO_4 + c_2 CaCl_2 ⟶ c_3 NaCl + c_4 CaSO_4 Set the number of atoms in the reactants equal to the number of atoms in the products for Na, O, S, Ca and Cl: Na: | 2 c_1 = c_3 O: | 4 c_1 = 4 c_4 S: | c_1 = c_4 Ca: | c_2 = c_4 Cl: | 2 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 1 c_3 = 2 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | Na_2SO_4 + CaCl_2 ⟶ 2 NaCl + CaSO_4
