Balanced equation

Balance the chemical equation algebraically: HOCl + NH_2OH ⟶ H_2O + HCl + N_2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 HOCl + c_2 NH_2OH ⟶ c_3 H_2O + c_4 HCl + c_5 N_2 Set the number of atoms in the reactants equal to the number of atoms in the products for Cl, H, O and N: Cl: | c_1 = c_4 H: | c_1 + 3 c_2 = 2 c_3 + c_4 O: | c_1 + c_2 = c_3 N: | c_2 = 2 c_5 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 = 2 c_3 = 3 c_4 = 1 c_5 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | HOCl + 2 NH_2OH ⟶ 3 H_2O + HCl + N_2
