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.
