| QUESTION | ANSWER |
|
1. All other things being equal, rank the intermolecular forces in order of increasing strength. |
1. dispersion forces < dipole-dipole interactions < hydrogen bonding < ionic bonding |
|
3. Can a molecule experience more than one intermolecular force at the same time? Why or why not? |
3. Yes, but one intermolecular force usually dominates. |
|
5. How many grams of solid water can be melted with 1.55 kJ of energy? |

|
7. Another way to minimize freezer burn is to wrap food tightly before freezing. Why would this minimize freezer burn? |
7. Water in the vapor phase has no space to evaporate into. |
|
9. Which do you think would have a higher surface tension—liquid neon or liquid krypton? Explain your answer. |
9. liquid krypton because it would have stronger dispersion forces |
