Balanced equation

Balance the chemical equation algebraically: CO_2 + Li_2O ⟶ Li_2CO_3 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 CO_2 + c_2 Li_2O ⟶ c_3 Li_2CO_3 Set the number of atoms in the reactants equal to the number of atoms in the products for C, O and Li: C: | c_1 = c_3 O: | 2 c_1 + c_2 = 3 c_3 Li: | 2 c_2 = 2 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 1 c_3 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | CO_2 + Li_2O ⟶ Li_2CO_3
