Question 1

How can you find volatility?

Answer 1

More pressure = higher volatility

*stronger molecular forces have less pressure

Question 2

How can you tell boiling point when given pressure?

Answer 2

When pressure hits 760 torr, 1 atm etc. that’s the boiling point.

Question 3

How to tell the melting point?

Answer 3

The stronger the IMF, the bigger the melting point

Question 4

How to tell which compounds have higher boiling points?

Answer 4

More electrons = higher boiling point.

Question 5

What force does a single noble gas have?

Answer 5

Dispersion

Question 6

How to tell if there is a hydrogen bonding force between molecules of own compound?

Answer 6

If F,O,N is touching Hydrogen.

Question 7

How to tell if there is a hydrogen bonding force between molecules of water?

Answer 7

If F,O,N is present.

Question 8

Difference between cohesion and adhesion?

Answer 8

• cohesion- intermolecular attraction between like molecules

* adhesion- attraction of unlike molecules

Question 9

How to solve two part reactions?

Answer 9

Add them together and make sure you can cancel out same ones.

Question 10

How to figure out Eq for standard formation reactions?

Answer 10

Take the physical states and balance them so they can equate to what you’re given.
