Chem 32: The First Exam

Back to the Chem 32 Virtual Manual

Following are links to sample problems, most of which are from past Chem 32 exams. These cover the topics you might expect to see on the first Chem 32 midterm on Tuesday, October 12th. The numbers of the problems invoking the listed concept are in parentheses. Explanatory texts can be accessed here if you need them, but try to focus on doing problems. If you want a periodic table to pop up in another window for you to refer to as you work, then click here. If you find any typos, errors, or explanations that are unclear, please email kaleeg@leland or add your comments/suggestions to the Chem 32 database and let me know so I can fix it before others encounter the problem.
