Week 8: Chemical Bonding and The Law

As we come to the end of our learning on the periodic table, we will now look at the relationship between the elements, chemical bonding, and the Law of Conservation of Matter. We spent the first two days of the previous week discussing the Law of Conservation of Matter, but this week we will get into more of the math behind it. Review these videos in preparation for class this week.
