Balanced equation

Balance the chemical equation algebraically: O_2 + CH3 + CH2OH ⟶ H_2O + CO_2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 O_2 + c_2 CH3 + c_3 CH2OH ⟶ c_4 H_2O + c_5 CO_2 Set the number of atoms in the reactants equal to the number of atoms in the products for O, C and H: O: | 2 c_1 + c_3 = c_4 + 2 c_5 C: | c_2 + c_3 = c_5 H: | 3 c_2 + 3 c_3 = 2 c_4 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 = (4 c_1)/5 - 7/5 c_4 = (6 c_1)/5 - 3/5 c_5 = (4 c_1)/5 - 2/5 The resulting system of equations is still underdetermined, so an additional coefficient must be set arbitrarily. Set c_1 = 3 and solve for the remaining coefficients: c_1 = 3 c_2 = 1 c_3 = 1 c_4 = 3 c_5 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 3 O_2 + CH3 + CH2OH ⟶ 3 H_2O + 2 CO_2
