Balanced equation

Balance the chemical equation algebraically: AgNO_3 + Ni ⟶ Ag + Ni(NO_3)_2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 AgNO_3 + c_2 Ni ⟶ c_3 Ag + c_4 Ni(NO_3)_2 Set the number of atoms in the reactants equal to the number of atoms in the products for Ag, N, O and Ni: Ag: | c_1 = c_3 N: | c_1 = 2 c_4 O: | 3 c_1 = 6 c_4 Ni: | 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 = 2 c_2 = 1 c_3 = 2 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 2 AgNO_3 + Ni ⟶ 2 Ag + Ni(NO_3)_2
