Balanced equation

Balance the chemical equation algebraically: H_2O + Mg + CsNO2 ⟶ NH_3 + Mg(OH)_2 + CsOH Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2O + c_2 Mg + c_3 CsNO2 ⟶ c_4 NH_3 + c_5 Mg(OH)_2 + c_6 CsOH Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, Mg, Cs and N: H: | 2 c_1 = 3 c_4 + 2 c_5 + c_6 O: | c_1 + 2 c_3 = 2 c_5 + c_6 Mg: | c_2 = c_5 Cs: | c_3 = c_6 N: | 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 = 3 c_3 = 1 c_4 = 1 c_5 = 3 c_6 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 5 H_2O + 3 Mg + CsNO2 ⟶ NH_3 + 3 Mg(OH)_2 + CsOH
