Balanced equation

Balance the chemical equation algebraically: Hg(NO_3)_2 ⟶ O_2 + NO_2 + HgO Add stoichiometric coefficients, c_i, to the reactants and products: c_1 Hg(NO_3)_2 ⟶ c_2 O_2 + c_3 NO_2 + c_4 HgO Set the number of atoms in the reactants equal to the number of atoms in the products for Hg, N and O: Hg: | c_1 = c_4 N: | 2 c_1 = c_3 O: | 6 c_1 = 2 c_2 + 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 2 c_2 = 1 c_3 = 4 c_4 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 2 Hg(NO_3)_2 ⟶ O_2 + 4 NO_2 + 2 HgO
