Physical Science 20 - Nov 26

Today we finished looking at enthalpy by studying Hess's Law.  This is where we were able to find the change in enthalpy of a reaction by breaking the reaction down into the parts that make it up.  We looked at the example with cellular respiration.  We then did 2 more examples from Assignment H4.  Tomorrow we will do another example and then have the rest of the class to work on Assignment H4.
