Practice Exams

Linked below are the midterm exams from the last time I taught CH142 (2015). That semester, we had to cover the solutions chapter and so you'll see that showing up on the first exam. Also, we did some of the chapter in different orders. As such, you'll have to find appropriate practice questions across more than one exam.

Exam 1, 2015 - Key

Exam 2, 2015 - Key

Exam 3, 2015 - Key

Practice exam videos

(These are short videos of Prof. Rice solving problems from the practice exams that are applicable to midterm exams)

Lecture videos

(These are short videos in which we go through some of the trickier concepts from lecture that you can watch and re-watch at your leisure)

Exam 3: Tuesday, April 25th, 5:00 PM, Keyes 105

The third exam will cover lecture (through Friday, 4/21), the reading (chapters 17:4-7, 23:1-3, 19, and 20:1-7), and the laboratory (through the week of 4/17).  Expect questions to come from all three sources.  As always, you should also be aware that we consider material from earlier in the semester and CH141 to be fair game for examinations in CH142. You will be provided a periodic table and useful equations and constants. You must bring the calculator specified for this course in the Colby bookstore.

Some recommendations:
  • It is always required to show all work for each problem. If there are steps that you feel you can skip, your logic must still be clear.
  • Redox balancing equations will be graded all or nothing!


Exam 2: Thursday, March 30th, 5:00 PM, Keyes 105 - Exam 2 KEY

The second exam will cover lecture (through Friday, 3/17), the reading (chapters 16 and 17:1-3), and the laboratory (through the week of 3/13).  Expect questions to come from all three sources.  You should also be aware (still) that we consider material from CH141 to be fair game for examinations in CH142. You will be provided a periodic table and other useful information. You must bring the calculator specified for this course in the Colby bookstore.


Exam 1: Wednesday, March 1st, 5:00 PM, Keyes 105 - Exam 1 KEY

The first exam will cover lecture (through Friday, 2/24), the reading (chapters 14 & 15), and the laboratory (through the week of 2/20).  Expect questions to come from all three sources.  You should also be aware that I consider material from CH141 to be fair game for examinations in CH142. You will be provided a periodic table and some useful constants. You must bring the calculator specified for this course in the Colby bookstore.
