Welcome to your first online lecture. Get your notepad out and write on top...Chapter 4, Lecture 7 (Review/Copper Cycle Lab).
When we started Chapter 4: Reactions in Aqueous Solutions on 2/24/20, we discussed that there were 3 types of reactions that we were going to cover:
- - Section 4.2: Precipitation Reactions,
- - Section 4.3 Acid-Base Reactions, and
- - Section 4.4: Oxidation Reduction Reactions
Review
