These are the answer keys for this semester's quizzes and exams (click on the following links to go to the page containing extra problems and the out-of-class assignments). If there is a hyperlink from an item, then an answer key for that item is available. All keys are in Adobe PDF format (see CHEM 121 home page for downloading information).

In the keys the following convention is used.  Answers and things that you should have written on the quiz or exam are shown in bold.  Notes that clarify an answer, or to point out an interesting fact, are in italics.
