H Chemistry 9.23.16

Today was the unit 3 test.

Homework: Read the article, “Sugar: an Unusual Explosion” and answer questions. Due Monday, 10/3.

H Chemistry 9.20.16

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.
