Balanced equation

Balance the chemical equation algebraically: H_2O + O_3Cl_2 ⟶ HClO2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2O + c_2 O_3Cl_2 ⟶ c_3 HClO2 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O and Cl: H: | 2 c_1 = c_3 O: | c_1 + 3 c_2 = 2 c_3 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 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | H_2O + O_3Cl_2 ⟶ 2 HClO2
