What happens to two water molecules after they come together to form a hydrogen bond-do they vibrate more rapidly or less rapidly?
 
  A) Since the bonding of the two water molecules results in a loss of kinetic energy, the molecules would vibrate less rapidly.
  B) Since the bonding of the two water molecules results in an increase of kinetic energy, the molecules would vibrate more rapidly.
  C) Since the bonding of the two water molecules results in no change in kinetic energy, the vibration of the molecules does not change.
  D) The formation of the hydrogen bond stabilizes both molecules. The vibration rate is therefore less rapid.

  A) CS2
  B) CF4
  C) SO2
