Balanced equation

Balance the chemical equation algebraically: Cu(NO_3)_2 + NaHCO_3 ⟶ H_2O + CO_2 + NaNO_3 + CuCO_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 Cu(NO_3)_2 + c_2 NaHCO_3 ⟶ c_3 H_2O + c_4 CO_2 + c_5 NaNO_3 + c_6 CuCO_3 Set the number of atoms in the reactants equal to the number of atoms in the products for Cu, N, O, C, H and Na: Cu: | c_1 = c_6 N: | 2 c_1 = c_5 O: | 6 c_1 + 3 c_2 = c_3 + 2 c_4 + 3 c_5 + 3 c_6 C: | c_2 = c_4 + c_6 H: | c_2 = 2 c_3 Na: | c_2 = c_5 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 = 1 c_4 = 1 c_5 = 2 c_6 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | Cu(NO_3)_2 + 2 NaHCO_3 ⟶ H_2O + CO_2 + 2 NaNO_3 + CuCO_3
