Because water molecules are polar and carbon dioxide molecules are nonpolar, question 9 options: water has a lower boiling point than carbon dioxide does. carbon dioxide cannot exist as a solid. attractions between water molecules are weaker than attractions between carbon dioxide molecules. water has a higher boiling point than carbon dioxide does.

The correct answer is: Water has a higher boiling point than carbon dioxide does.

Explanation:

Ok, because water is a polar molecule and its bonds are hydrogen bonds, this causes its boiling point to be higher than that of carbon dioxide, since hydrogen bonding is more resistant to rupture (in this case when heating), on the other hand carbon dioxide has convalent bonds, which are weaker. Therefore, the water will have a boiling point higher than that of carbon dioxide, since it costs more to break its polar bonds. This will also be true for any molecule that has hydrogen bonding links and is polar.
