Exam #1  covers the material in chapters 7 and 8 and labs 1-3. Stuff to concentrate on while reviewing:

  1. Understand These Concepts. Chapter 7: 1, 3-7, 9-12 (only s and p orbitals for #12) on page 287. Chapter 8: 1-19 on page 322

  2. Master These Skills. Chapter 7: 1-6 on page 287. Chapter 8: 1-6 on page 323

  3. Key Equations and Relationships: Chapter 7: 7.1 - 7.6 on page 288. Chapter 8: 8.1 and 8.2  on page 323. (These equations will be given to you on the exam, but you need to know when and how to use them!)

  4. All ALE's for chapters 7 and 8

  5. Have a go at this practice exam. NOTE:  This practice exam is intended to give you an idea of the kind of questions to expect. The actual exam given WILL differ slightly from this one! For example, concentrate on understanding and applying the concepts/principles discovered by the famous physicists/chemists mentioned on the practice exam, rather than memorizing the individuals responsible for discovering each concept/principle.

  6. (the previous links were broken!!)  Here are some good multiple choice Practice Questions: focus on the questions for chapters 7-8 from the Silberberg Online Learning Center http://highered.mcgraw-hill.com/sites/0072396814/student_view0/index.html . Select a chapter (7 or 8) from the pull-down menu on the left and then click on either of the interactive quizzes. These questions are intended to help you identify areas of strength and areas where further review may be needed.
