Physical Science 20 - March 24

Today, after we went over the answers to questions #1-4 on Assignment C24, we did a couple more stoichiometry problems.  These examples were on slides 12 and 13 in the powerpoint.  Students then had a chance to work on #5-8 in C24 after we had a talk about lab safety.  Tomorrow we will start Lab C4.  We are also going to finish Assignment C24.
