Balanced equation

Balance the chemical equation algebraically: CH_4 + HOCl ⟶ H_2O + CH_3Cl Add stoichiometric coefficients, c_i, to the reactants and products: c_1 CH_4 + c_2 HOCl ⟶ c_3 H_2O + c_4 CH_3Cl Set the number of atoms in the reactants equal to the number of atoms in the products for C, H, Cl and O: C: | c_1 = c_4 H: | 4 c_1 + c_2 = 2 c_3 + 3 c_4 Cl: | c_2 = c_4 O: | 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 = 1 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | CH_4 + HOCl ⟶ H_2O + CH_3Cl
