Balanced equation

Balance the chemical equation algebraically: NaHCO_3 ⟶ Na2CO3CO2H2O Add stoichiometric coefficients, c_i, to the reactants and products: c_1 NaHCO_3 ⟶ c_2 Na2CO3CO2H2O Set the number of atoms in the reactants equal to the number of atoms in the products for C, H, Na and O: C: | c_1 = 2 c_2 H: | c_1 = 2 c_2 Na: | c_1 = 2 c_2 O: | 3 c_1 = 6 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_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 2 c_2 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 2 NaHCO_3 ⟶ Na2CO3CO2H2O
