Chemistry Semester Exam Study Guide
Spring 2014
The exam for Chemistry is scheduled for Thursday, May 29th at 11am in the Theater. This exam
for will be a comprehensive exam encompassing all material we have covered since August. This study
guide is intended to be an outline of the major topics presented in this class. It is not worth any points
and will not be collected. It is also not an extensive list of material, but a guide to prompt your studying.
You are responsible for all of the material we have covered in chapters 1-10 in addition to any special
topics presented and/or discussed. If you have questions about a particular topic, don’t be afraid to ask
in class or see me for help. Teaching and quizzing one another will serve very useful in demonstrating
your mastery of the material, so study together and ask questions.
