Balanced equation

Balance the chemical equation algebraically: AgNO_3 + CrCl_3 ⟶ AgCl + CrN_3O_9 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 AgNO_3 + c_2 CrCl_3 ⟶ c_3 AgCl + c_4 CrN_3O_9 Set the number of atoms in the reactants equal to the number of atoms in the products for Ag, N, O, Cl and Cr: Ag: | c_1 = c_3 N: | c_1 = 3 c_4 O: | 3 c_1 = 9 c_4 Cl: | 3 c_2 = c_3 Cr: | c_2 = 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 = 3 c_2 = 1 c_3 = 3 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 3 AgNO_3 + CrCl_3 ⟶ 3 AgCl + CrN_3O_9
