Balanced equation

Balance the chemical equation algebraically: H_2SO_4 + C_12H_22O_11 ⟶ H_2O + CO_2 + SO_2 + C Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2SO_4 + c_2 C_12H_22O_11 ⟶ c_3 H_2O + c_4 CO_2 + c_5 SO_2 + c_6 C Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, S and C: H: | 2 c_1 + 22 c_2 = 2 c_3 O: | 4 c_1 + 11 c_2 = c_3 + 2 c_4 + 2 c_5 S: | c_1 = c_5 C: | 12 c_2 = c_4 + 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_2 = 1 and solve the system of equations for the remaining coefficients: c_2 = 1 c_3 = c_1 + 11 c_4 = c_1/2 c_5 = c_1 c_6 = 12 - c_1/2 The resulting system of equations is still underdetermined, so an additional coefficient must be set arbitrarily. Set c_1 = 12 and solve for the remaining coefficients: c_1 = 12 c_2 = 1 c_3 = 23 c_4 = 6 c_5 = 12 c_6 = 6 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 12 H_2SO_4 + C_12H_22O_11 ⟶ 23 H_2O + 6 CO_2 + 12 SO_2 + 6 C
