Balanced equation

Balance the chemical equation algebraically: CH_3CO_2H + CH_3CH_2OH ⟶ H_2O + C_4H_8O_2 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 CH_3CO_2H + c_2 CH_3CH_2OH ⟶ c_3 H_2O + c_4 C_4H_8O_2 Set the number of atoms in the reactants equal to the number of atoms in the products for C, H and O: C: | 2 c_1 + 2 c_2 = 4 c_4 H: | 4 c_1 + 6 c_2 = 2 c_3 + 8 c_4 O: | 2 c_1 + c_2 = 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_1 = 1 and solve the system of equations for the remaining coefficients: c_1 = 1 c_2 = 1 c_3 = 1 c_4 = 1 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | CH_3CO_2H + CH_3CH_2OH ⟶ H_2O + C_4H_8O_2
