Chap 16 and 17

Question 0

What do colligative properties depend on?

Answer 0

They ONLY depend on, the AMOUNT of solute in solvent-NOT the type of solute!!

Question 1

In chapter 16, what do you NEED to know?

Answer 1

You need to know, the colligative properties!! like; boiling point, freeIng point depression.

Question 2

You need to know..?

In chap 17

Answer 2

You need to know, the thermal energy, phase changes, enthalpy, and that energy is never lost.

Question 3

What’s thermal energy?

Answer 3

Thermal energy( related to TEMPERATURE) is transferred from ht to cold objects in the form of HEAT!

Question 4

What do you need to Know about phase changes?

Answer 4

Phase changes are either ectothermic or endothermic. Depending on if heat is released ( like, freezing) or absorbed( like boiling).
If released; exo and if not endo

Question 5

What’s enthalpy?

Answer 5

Enthalpy is a fact word for HEAT!

It’s variable, Delta H( if positive it’s ENDO. If negative it’s EXO)
