Week 5: Section B Schedule
This week we will start by finishing chapter 4 with Oxidation and Reduction Reactions and then take a brief detour into chapter 20 to learn how to balance Redox reactions.
Then we will begin our discussion on how energy is transferred due to chemical reactions with Thermochemistry.
Reminder: First Exam is Monday, October 1st from 5pm until 7pm.
Because of the exam, you have a few extra days to do Homework Assignment #5. That is due on Sunday, 10/7.

Week 4: CH141 B Schedule
Which chemical reactions happen in our water sources like the the Belgrade Lakes? How does the fluoridation of drinking water protect tooth enamel? How do plants react when eaten by a caterpillar? To answer these questions (and many more!) we first need to explore how chemistry happens in the aqueous phase!
This week we will learn about different types of reactions that can happen when molecules are dissolved in water.
Reminder: Our first exam will happen on Monday, Oct. 1st from 5pm -7pm. More information can be found here. There will be an optional review session on Sunday, September 30 starting at 7:00 pm in Keyes 105.
Study Tip of the Week: Do you and your study group feel confused about a practice problem? Bring the questions and your whole study group to office hours or email me to schedule a meeting time. We can figure it out together!
Materials for class will be posted here throughout the week.
