<strong>Chemistry</strong> <strong>Midterm</strong> <strong>Review</strong> <strong>2009</strong><br />
The midterm will consist of 150-175 multiple choice and matching questions.<br />
Students will be provided a periodic table, energy level diagram, and scrap<br />
paper. Students are required to bring a non-graphing calculator, pencils<br />
and erasers.<br />
