Rainbow Lab Prep

1. Boo Bubbles!
2. Rainbow Lab Prep
Using the information for the 5 stations, choose which stations you will test (you don’t need to test all 5) and be able to identify what caused the stress, collision theory, rate changes, equilibrium shift, and color you should observe.

Le Chatelier’s Principle

1. Demo: large ladle and small soup spoon equilibria. Even though they end up with different amounts of water, they will transfer water at the same rate when they reach equilibrium
2. Go over Equilibrium #1 Worksheet
3. I will be able to use Le Chatelier’s Principle to predict and explain equilibrium shifts
Try looking at these animations:

4. Read Section 15.7 and do Q #61, 62
5. Do: Equilibrium #2 Worksheet

Separating Mixtures

1. We drew the “Tree of Chemistry”
2. I will be able to choose and describe different ways to separate mixtures.
3. Video: “Tutorial: Paper and Thin Layer Chromatography”


4. Begin Chromatography Lab Prep: cut strips, label, spot colors
5. Continue column notes (finish sections 4-6)
6. Unit 3 Test – Thurs. Nov.6

Le Chatelier’s Principle

1. Demo: large ladle vs. soup spoon. At some point, they will be transferring water to each other’s container at the same rate.
2. In class worksheet: Equilibrium #1. Predict whether the reaction will not react, go to completion, or reach equilibrium using the factors of enthalpy and entropy.
3. I will be able to use Le Chatelier’s Principle to predict shifts in equilibrium.
4. Read section II.4. Do: Q#17-28 (choose 3-5 Q’s)
Next class, we will use Le Chatelier’s principle to help determine what to do in a lab activity.

Ch14 Test

1. Hand in your chapter 14 notes and chapter 14 review worksheet (with corrections and/or reflection).
2. Students wrote the chapter 14 test.
Next class: we will go over Equilibrium #1 Worksheet and look at Le Chatelier’s Principle.

Physical and Chemical Changes

1. I will be able to distinguish between physical and chemical changes.
2. Activity: mixing chemicals and determining whether the reaction has a physical or chemical change.
3. Continue column notes for Unit 3. Your goal is to finish to the end of section 3 for next class.
4. Do: Q# 3,5,12 for section 1; Q#13, 15, 17 for section 2, and Q# 33, 36, 39, 44 for section 3.

Unit 1 Test

Happy Mole Day to You! Celebrate National Chemistry Week with some Candy (this year’s theme is the Chemistry of Candy) You can google all sorts of Candy Chemistry–youtube videos, etc…

1. Today, students wrote the Unit 1 test on Reaction Kinetics.
Next class, we will continue with Equilibrium (Unit 2)

Intro to Equilibrium

1. Any questions from chapter 14?
2. Ch 14 Test Outline: about 20-30 mc questions; written section will include rate law, mechanisms, energy in reactions
3. Begin reading ch15 sections 1-3. I will be able to identify and describe equilibrium systems.
