WOOOOOHOOOOOO! This is your last Chem 109 Lecture!!! We will finish chapter 11 today. As promised, I am giving you Friday OFF! BE SURE to take the attendance/comprehension quiz for lecture 40 since it is worth double points so that you can earn the 5 points that would have been on a quiz for Friday's lecture.

But first, lecture 40!

In this lecture we will discuss fractional distillation and colligative properties. The colligative properties are properties that result from the presence of a solute in a solvent and they are: decreased vapor pressure, elevated boiling point, depressed freezing point, and osmotic pressure.

The materials for this lecture are:

Chapter 11 slides (slides 7-18)
