Today was the unit 3 test.

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

Today we did a scavenger hunt review game.

Here is the answer key for the unit 3 review.

Test tomorrow – study!!!

Today we did a lab on Lewis Structures and Molecular Geometry.

We also worked on the review for the unit 3 test, which is on Friday!

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 we discussed properties of ionic compounds and how to draw Lewis structures for covalent compounds. See the power point from Friday, 9.16.
