Review Sheet for Exam Two, General Chemistry II 111, Lycoming College, Dr.
The exam will be held Friday, March 11, 2005, in Academic Center D-001 (where Chemistry 110 exams were also held last semester). You can start the exam at about 11:20 AM (just after the previous class period ends) and must finish by 12:45 PM (when the next scheduled class period starts). Please sit so that there is an empty chair / seat between you and the next nearest person in every direction.
The exam will have a periodic table with it. There will be a matching section with possibly useful equations. Constants and required data will be provided. Possible exam question formats include multiple choice, matching, short answer, essay, and calculations.
You are allowed to have pen or pencil with eraser and a calculator. No programmable calculators are allowed – everyone must show me their calculator to get an exam. If you must use a programmable calculator, I will clear the memory on it first (but you will have to wait if others have questions or needs). No other materials are allowed out during the exam. Any personal electronic devices being used (cell phone, PDA, music headphones, etc.) will be confiscated until the end of the exam and may result in a penalty on the exam.
Erika Pfaunmiller, our class study group facilitator, should run two review sessions the week of the exam. Sessions are generally held in Heim G41 at 9 PM, on Tuesdays and Thursdays. Exact dates and times will be announced the week of the exam.
I will run one review session in Heim G11 from 8:30 to 10 PM on Wednesday, March 9, 2005. This is the large lecture room across the hall from our classroom.
MATERIAL COVERED ON EXAM TWO
The exam will cover all material from lectures through Monday, March 7, 2005.
The new material covered in the textbook (Hill and Petrucci, General chemistry 3rd ed.) since exam one is: Chapter 15 sections 1-6 (assumes what we will cover Monday, March 7); Chapter 14 sections 1-5 (all); Chapter 13 sections 6-11.
New homework problems since exam one include: Chapter 15: 21, 24, 30, 33, 35, 38, 41, 45, 48, 49, (definitely) 53, 56, 59, 64, (tentatively). Chapter 14: 22, 25, 29, 32, 35, 38, 41, 43, 44, 47, 49, 52, 54, 57, 59, 62, 66, 69, 72, 89. Chapter 13: 43, 46, 52, 55, 58, 61, 65, 67, 68, 69, 72, 85.

Previously covered homework problems include: Chapter 11: 13, 64, 69, 70, 91 (only count atoms in unit cell); Chapter 12: 21, 24, 25, 28, 29, 32, 33, 36, 38, 39, 41, 43, 45, 48, 51, 53, 55, 57, 58, 62, 63, 67, 70, 71, 76, 77, 79; and from Chapter 13: 24, 27, 31, 34, 37, 40, 41, 48, 85a,b.
