CuAgNO3 ⟶ AgCuNO3

Balance the chemical equation algebraically: CuAgNO3 ⟶ AgCuNO3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 CuAgNO3 ⟶ c_2 AgCuNO3 Set the number of atoms in the reactants equal to the number of atoms in the products for Cu, Ag, N and O: Cu: | c_1 = c_2 Ag: | c_1 = c_2 N: | c_1 = c_2 O: | 3 c_1 = 3 c_2 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 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | CuAgNO3 ⟶ AgCuNO3
