IMF 2 BOILING POINT (CHEESE)

Question 1

Electrostatic interactions between molecules

Answer 1

Intermolecular forces

Question 2

Atoms within a molecule make what with each other?

Answer 2

Covalent and Ionic bonds

Question 3

Large ionic solids are held by?

Answer 3

Ionic bonds

Question 4

Ionic bonds are strong why?

Answer 4

They have formal charges

Question 5

Covalent bonds in a water molecule are?

Answer 5

Polar

Answer 9

Negative Charges

Question 10

When dipoles interact with each other

Answer 10

Dipole Dipole Interactins

Question 11

When dipoles generated by NH3, H20, HF interact with each other

Answer 11

Greater than partial charge? The greater the what?

Answer 13

Interaction

Question 14

Greater the interaction, greater the what?

Answer 14

The partial charge

Question 15

But partial charges are not stronger than?

Answer 15

Formally charged particles

Question 16

Any substance can do this?

Answer 16

Van der Waals Forces

Question 17

Question 28

Energy left inside an element is what?

Answer 28

Is the needed heat energy in order for it to change phase

Question 29
