Balanced equation

Balance the chemical equation algebraically: NaCl + Cu(NO_3)_2 ⟶ NaNO_3 + CuCl_2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 NaCl + c_2 Cu(NO_3)_2 ⟶ c_3 NaNO_3 + c_4 CuCl_2 Set the number of atoms in the reactants equal to the number of atoms in the products for Cl, Na, Cu, N and O: Cl: | c_1 = 2 c_4 Na: | c_1 = c_3 Cu: | c_2 = c_4 N: | 2 c_2 = c_3 O: | 6 c_2 = 3 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_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 NaCl + Cu(NO_3)_2 ⟶ 2 NaNO_3 + CuCl_2
