Physical Science 20 - Sept 15

In class today we talked about some homeroom things that took a little while. We then went over Assignments C9 and C10 on balancing.  As well, I reviewed the lesson from Friday that the sub taught you.  We will go over the answers to Assignment C11 tomorrow.  As well, there are 5 videos in the course link that I want you to watch in preparation for class tomorrow.  We will be learning about the types of reactions.  Those videos will help refresh your mind about types of reactions.
