Balanced equation

Balance the chemical equation algebraically: H_2O + Cl_2 + Na_2S_2O_3 ⟶ H_2SO_4 + HCl + NaCl Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2O + c_2 Cl_2 + c_3 Na_2S_2O_3 ⟶ c_4 H_2SO_4 + c_5 HCl + c_6 NaCl Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, Cl, Na and S: H: | 2 c_1 = 2 c_4 + c_5 O: | c_1 + 3 c_3 = 4 c_4 Cl: | 2 c_2 = c_5 + c_6 Na: | 2 c_3 = c_6 S: | 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_3 = 1 and solve the system of equations for the remaining coefficients: c_1 = 5 c_2 = 4 c_3 = 1 c_4 = 2 c_5 = 6 c_6 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 5 H_2O + 4 Cl_2 + Na_2S_2O_3 ⟶ 2 H_2SO_4 + 6 HCl + 2 NaCl
