Physical Science 20 - Sept 10

Students handed in Assignment C8 today.  We then started looking at chemical reactions and the different parts of one.  We talked about the Law of Conservation of Mass and what that directly relates to.  We then moved into balancing chemical equations.  This was review for most people but we did learn some tricks for balancing equations for efficiently.  Students then worked on Assignment C9 for the remainder of the class.  This will be checked tomorrow.  Tomorrow we will look at how to write a chemical equation from a word equation.
