Water has a higher boiling point than expected because a. there is so much water vapor in the atmosphere. b. water molecules are not very massive. c. hydrogen and oxygen form single covalent bonds. d. of the strong attractions between polar water molecules

The correct answer is C. Water has a higher boiling point than expected because hydrogen and oxygen form single covalent bonds. Molecules of water is bound together by strong attractions which needs high energy to break resulting to a higher boiling point of water than most substances.

The correct answer is "atomic weight".

The answer is a a and x i just took the quiz and it was right
