For this topic, you will select two problems from the Chemistry: Atoms First, OpenStax text (in the link there is a book), __ one problem from each of the following two problem sets__:

**For Problem 1: You MUST select a problem from the end of the chapter “Exercises” from Chapter 7: Problems 43-95.****For Problem 2: You MUST select a problem from the end of the chapter “Exercises” from Chapter 9: Problems 39-86.**

You need to:

*show work to find solution (you can use an embedded image or the * Σ* button on the Rich Text Editor if appropriate).

*explain in the text how you approached and worked through the problem.

Ideally, you will choose problems that you had a hard time solving until something is selected (which you would then explain–what you figured out that you did wrong, etc.). Either way, you should *lead a discussion* about the problem. This will help everyone go through the thought process of these problems, see different ways that students set them up, compare approaches, maybe learn new strategies and hints, recognize mistakes, etc. If you cannot solve the problem at first, no worries, your classmates and myself will give you help you along and you can edit your problem until it is due. If you are having trouble, show your work and explain where you are getting stuck. Remember, you are not getting graded on whether you solve the problems correctly, but rather the attempt you make and the discussion you have with us related to it. So it will likely be more beneficial to you to select challenging problems with which you need help as opposed to easy ones that you can already solve.
