Ineed someone to see if my answers are correct!

1. for solutions, colligative properties depend only on the number of dissolved particles in a given volume and do not depend on the identity of the solute.

a. true
b. false < my choice

2. what number of particles will nh3 make in a solution.

a. 1
b. 2 < my choice
c. 3
d. 4

3. what number of particles will c6h12 make in solution.

a. 1
b. 2
c. 3
d. 4 < my choice

4. boiling occurs when the vapor pressure of a liquid equals the atmospheric pressure. in the high altitude city of denver, the boiling point of water is

a. > 100°c < my choice
b. 100°c
c. < 100°c

5. what number of particles will al(no3) 3 make in solution

a. 1 < my choice
b. 2
c. 3
d. 4

6. what number of particles will babr2 make in solution.

a. 1
b. 2
c. 3 < my choice
d. 4

7. determine which compound would raise the boiling point of water the most.

a. 2.0 m (nh4)3po4
b. 2.0 m nacl
c. 2.0 m cacl2
d. 2.0 m kbr < my choice

8. determine which compound would lower the freezing point of water the most

a. 2.0 m kl
b. 2.0 m k2so4 < my choice
c. 2.0 m nacl
d. 2.0 m kbr

if any are wrong let me know which is the correct answer and why

Explanation:

1. The given statement is true.

Colligative properties are properties of the ideal solution which depends upon the amount or particles of solute dissolved in fixed amount of solvent. These properties do not depend upon the nature of the solute.

2. Ammonia when dissolves in water gives two particles:

3. Hexane is an non polar molecule. when dissolved in water its structural unit gives only 1 particle.

4. At higher altitudes atmospheric pressure decreases.Vapor pressure of a liquid and atmospheric pressure directly linked to each other which means that liquid will boil at lower temperature than it normal boiling temperature when boiled in  higher altitudes.

So, water will boil at temperature lower than 100° C.

5. is ionic compounds which dissociated into 4 particles when dissolved in water.

6. is ionic compounds which dissociated into 3 particles when dissolved in water.

7. The correct answer is option A.

i = van't Hoff Factor

Larger value i more will be elevation in boiling point of the solvent.

1 molecule of Ammonium phosphate dissociate into 4 particles when dissolved in water.

8.The correct answer is option B.

i = van't Hoff Factor

Larger value i more will be depression in freezing point of the solvent.

1 molecule of potassium sulfate dissociates into 3 particles when dissolved in water.
