Thursday January 27, 2010
Time: 10:00 – 11:30 am
1) What is the make-up of the Exam?
Part A Multiple Choice Questions (28)
Part B Short Essay (4) these will come from old AP exams
2) What does the Exam Cover?
Everything from the beginning of the year.
From the Review Book (AP Chemistry 4th Edition)
Look at the following chapters Stoichiometry, Thermodynamics, Equilibrium, Acids and Bases and
Kinetics. I was able to take some multiple choice questions word for word from these chapters.
(Numbers in parenthesis indicate number of multiple choice questions)
* Indicates material covered on Part II
