Looks like I missed posting after Monday's class. Oop.
We're elbow-deep in enthalpy at this point, today we worked through another couple problems in which we calculated the enthalpy of reaction, and used the enthalpy/heat/energy liberated by a reaction to heat up a block of granite in a heat capacity problem. We also worked through an example of a multi-step reaction and the realtionship between the enthalpy of each step and the overall enthalpy of the net reaction. This is Hess' Law, and is basically an example of how state functions work: the path doesn't matter, just the starting and ending points.
A new Mastering Chemistry is posted, due Monday. Don't wait until the last minute, our next exam is next Wednesday. As I mentioned in class today, Exam #3 will only cover through Chapter 6, we'll roll Chapter 7 into the next exam.
