Chemistry: Semester 1 Final Exam Study Guide
Part 1 of 2 (Units 1-3)
Note: You will be allowed to use the following materials on the Final Exam: the Periodic Table
with Polyatomic Ions Naming Sheet, and a scientific calculator. To prevent any cheating, you will
not be allowed to use a graphing calculator (you can trade it in for one of my class-set scientific
calculators) and/or share Exam materials with a class mate. It is your responsibility to make
sure you have everything you need for the Exam on the Exam day! If you’ve lost/misplaced your
Periodic Table and Polyatomic Naming Sheet, it is your responsibility to Xerox a copy
(preferably in the library) from a classmate. Majority of the questions on the Final will be
multiple choice, and the rest will be calculation type of problems where you must show ALL
WORK and report your final answer in the correct number of significant figures. All of the
formulas will be provided on the Final. Be sure to read the directions carefully on the Final!!!
