Today we took the unit 3 test.

Homework: Read chapter 10 on Gases.

Today, we reviewed and practiced writing Lewis Structures. We did the following 6 structures in class (for a grade)

1. CH2Cl2

2. NH3

3. H2S

4. C2H4

5. C2H6

6. N2

We also discussed moving from a Lewis Structure to the molecules 3-D molecular geometry based on the VSEPR theory (See the power point from yesterday.).

We then determine the molecular geometry for the molecules above.

We have a lab tomorrow.

Today you guys picked random test questions from a container and answered them as a group.

Here are the correct answers to it. You guys did really well.
