  1. Giải thích các bước giải:

     (1) C12H22O11 + H2O -> C6H12O6 + C6H12O6

    (2) C6H12O6-> 2C2H5OH +2CO2

    (3) C2H5OH + O2 -> CH3COOH + H2O

    (4) CH3COOH + C2H5OH -> H2O+CH3COOC2H5

    (5) CH3COOC2H5 + NAOH -> C2H5OH + CH3COONA

    (6) CH3COONA + H2O -> CH3COOH + NAOH

    (7) CH3COOK + NAOH -> CH4 + K2CO3 + NA2CO3

    (8) CH4 +O2 -> CO2 +2H2

    (9) 2CO2 + 3H2O -> C2H5OH + 3O2
