Honors Chemistry Chapter 1 Test

Study Guide

NOTE:

This review sheet should prepare you extremely well for your chapter 1 test. HOWEVER, please note that I reserve the right to include any information contained in your notes, homework assignments, quizzes, or textbook readings on this test. This review sheet should only be used as a tool to help you prepare for the test…it is not an “all-encompassing” document!!
