Balanced equation

Balance the chemical equation algebraically: FeCl_3 + AgNO_3 ⟶ Fe(NO_3)_3 + AgCl Add stoichiometric coefficients, c_i, to the reactants and products: c_1 FeCl_3 + c_2 AgNO_3 ⟶ c_3 Fe(NO_3)_3 + c_4 AgCl Set the number of atoms in the reactants equal to the number of atoms in the products for Cl, Fe, Ag, N and O: Cl: | 3 c_1 = c_4 Fe: | c_1 = c_3 Ag: | c_2 = c_4 N: | c_2 = 3 c_3 O: | 3 c_2 = 9 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 = 3 c_3 = 1 c_4 = 3 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | FeCl_3 + 3 AgNO_3 ⟶ Fe(NO_3)_3 + 3 AgCl
