Balanced equation

Balance the chemical equation algebraically: H_2O + O_2 + CO_2 + Cu ⟶ Cu(OH)_2 + CuCO_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2O + c_2 O_2 + c_3 CO_2 + c_4 Cu ⟶ c_5 Cu(OH)_2 + c_6 CuCO_3 Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, C and Cu: H: | 2 c_1 = 2 c_5 O: | c_1 + 2 c_2 + 2 c_3 = 2 c_5 + 3 c_6 C: | c_3 = c_6 Cu: | c_4 = c_5 + c_6 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_3 = 2 c_2 - 1 c_4 = 2 c_2 c_5 = 1 c_6 = 2 c_2 - 1 The resulting system of equations is still underdetermined, so an additional coefficient must be set arbitrarily. Set c_2 = 1 and solve for the remaining coefficients: c_1 = 1 c_2 = 1 c_3 = 1 c_4 = 2 c_5 = 1 c_6 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | H_2O + O_2 + CO_2 + 2 Cu ⟶ Cu(OH)_2 + CuCO_3
