1.     A. Hydrophilic salt
        B. Hydrophilic anion
        C. Hydrophilic short-chain alcohol
        D. Hydrophobic nonpolar organic molecule

2.    c, sponatenous at  all temperatures mean both entropy and enthalpy are favorable
3.    d, the higher K means the reaction goes to products the most
4.     (a) 2CH₃OH(l) + 3O₂(g) --> 2CO₂(g) + 2H₂O(g) or CH₃OH(l) + 3/2O₂(g) --> CO₂(g) + H₂O(g)
        (b) For ONE mole of methanol:
        2 mole(-228.6 kJ/mole) + (-394.4 kJ/mole) - (-166.4 kJ/mole) = - 684 kJ/mole
        (c) Yes, DG^o<0
5.     0.065 moles  x 5.6 L  x   46 g   = 17 g
                    L                      mole

6.    Reaction is spontaneous when DG^o<0
        DG^o = DH^o  - TDS^o= 0
        T = DH^o = 119000/263 = 452 K
