CHEM 400 Prerequisite Practice

Here are some reviews and practice sets for SOME of the material in which you are expected to be competent BEFORE starting CHEM 400. You should read through the reviews rather than just trying problems as there are hints and methods that you might find useful. For reviews and extra problems, you should attempt the work BEFORE looking at the keys. Just staring at the questions and then looking at the answers will do you absolutely no good. For the PowerPoints found on this page, they will be most useful of viewed in "slide show" mode through either PowerPoint or Google slides.
