Chem 109 Supplemental Study Modules

To the User: This web site is intended to help my students succeed in my Fundamentals of Chemistry course. These problem set/study modules are for practice. They include answer keys with worked out answers to the initial examples and just answers to later examples.

"Reflection" questions

Each exercise also includes a list of "reflection" questions. These are based on modern learning theory and are intended to aid student success - Please think about them and answer them in writing during and/or after each exercise to optimize your learning
