We started by looking at a problem finding the heat of combustion for acetylene in oxygen. The approach was to draw the bond structure determine the number of each type. There were coefficients in front of some terms in the reaction as well. The heat of combustion for the exothermic reaction was negative.
Looked at a few problems that were closely linked to physics including the photo electric effect and talked about the relationship of wavelength, frequency, and the speed of light. Understanding physics will make parts of chemistry make more sense.
Looked at hybridization and resonance and did a problem with the electron configuration of Chromium.
A number of things in chemistry need to be committed to memory.
