Physical Science 20 - Feb 3

Today we went over assignment C1. I didn't check this assignment and we didn't go through all of the answers.  Students are to access the answer keys if they want to check their work.  The answer keys are found in the Chemistry folder under the Physical Science 20 Course Notes link along the side. We learned about ionic compounds today and how to write formulas for them.  This involved balancing ionic charges.  This was all covered on slides 31-42 on the Chemistry Notes powerpoint. Students then had the rest of class to work on Assignments C2. We will be taking this up tomorrow and moving on and looking at polyatomic ions as well as multiple cationic charges.
