Balanced equation

Balance the chemical equation algebraically: Al + AgNO_3 ⟶ Ag + Al(NO3)2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 Al + c_2 AgNO_3 ⟶ c_3 Ag + c_4 Al(NO3)2 Set the number of atoms in the reactants equal to the number of atoms in the products for Al, Ag, N and O: Al: | c_1 = c_4 Ag: | c_2 = c_3 N: | c_2 = 2 c_4 O: | 3 c_2 = 6 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 2 c_3 = 2 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | Al + 2 AgNO_3 ⟶ 2 Ag + Al(NO3)2
