IMF

Question 1

Solution

Answer 1

A homogenous mixture of a solute dissolved in a solvent (NaCl)aq

Question 2

Solute

Answer 2

The substance that is dissolved NaCl(s)

Question 3

Solvent

Answer 3

The substance in which a solute in dissolved in

Question 4

Stronger IMF’s

Answer 4

Higher melting/boiling points…adding energy breaks the IMF forces between molecules, allowing phase change

Question 5

Changing the vapor pressure

Answer 5

Changes the boiling point

Question 6

Temperature increases

Answer 6

Vapor pressure increases

Question 7

Liquids with high VP

Answer 7

Have weake IMF’s

Question 8

Strongest IMF

Answer 8

Ethanoic Acid

Question 9

Weakest IMF

Answer 9

Propanone

Question 10

Liquids with low VP

Answer 10

Have strong IMF’s

Question 11

Larger molecules

Answer 11

Have strong IMF’s than smaller ones

Question 12

Larger molecules have lower melting/boiling points than smaller ones

Answer 12

False.

Question 13

Which IMF are responsiblibe for the high boiling point of water?

Answer 13

Hydrogen Bonding

Question 14

Which IMD are found between PCl3 molecules?

Answer 14

Dipole-Dipole

Question 15

Which molecules would have LD forces of attraction between them?

Answer 15

CH4

Question 16

Which would have molecule-ion forces of attraction?

Answer 16

NaCl(aq)

Question 17

Temperature and solubility of solid solutes

Answer 17

Increased temperature increases solubility of solids

Question 18

Temperature and solubility of gaseous solutes

Answer 18

Increased temperature decreases solubility of gases

Question 19

Pressure and solubility of gaseous solutes

Answer 19

Increased pressure increases solubility of gases

Question 20

The concentration of ions and freezing point

Answer 20

Increased concentration of ions decreases freezing point

Question 21

Solids have

Answer 21

higher IMF’s than liquids and gases because atoms are more tightly packed in a solid.
