Answer 3

0.51 degrees C per kg of water

Question 4

One mole of particles will result in how much freezing point depression?

Answer 4

1.86 degrees C per kg of water

Question 5

Name the ionic compounds that are NOT soluble (with exceptions)

Answer 5

Carbonate (CO3)
Phosphate (PO4)
Sulfide (S)
Hydroxide (OH)

Question 6

Boiling point elevation

Answer 6

0.51/mole of particles

per 1kg solution

Question 7

Freezing point depression

Answer 7

1.86/mole of particles

per 1kg solution

Question 8

Rate of reaction formula?

Answer 8

Change in concentration divided by change in time. Reactants are negative (because they are used up) products are positive.
