Here you can find reading guides that were created by Montgomery College faculty for undergraduate general chemistry students to use to guide their reading of OpenStax Chemistry. These guides are closely aligned with chapters 1-11 and were designed for use in the first semester sequence of general chemistry. They can be used in a flipped-style classroom where students complete them before the lecture. Or they can be used to reinforce important topics learned in class. Each study guide has fill-in-the blank style questions, as well as links to videos where similar problems are worked through. Finally, suggested practice problems relevant to the topic of each study guide are listed at the end.

We now know how to analyze pure compounds, but what if we have a mixture? Spectrophometry becomes quite complex when dealing with multiple species of compounds at once. In order to purify a compound we can separate if from a mixture based on its intrinsic chemical properties. Remember that fluorescein is negatively charged at a pH above pKa of the carboxyl group. We can take advantage of this fact and use its attraction to positive charges to separate it from other molecules. In ion-exchange chromatography, we will use a stationary phase with a positive charge, allowing negatively charged molecules to bind and positively charged species to flow through. We can then disrupt this interaction and retrieve our now-purified molecule, and use spectrophotometric analysis of our purified fractions to determine how well we were able to separate our molecules.

Here you can find reading guides that were created by Montgomery College faculty for undergraduate general chemistry students to use to guide their reading of OpenStax Chemistry. These guides are closely aligned with chapters 12-17 and 21 and were designed for use in the second semester sequence of general chemistry. They can be used in a flipped-style classroom where students complete them before the lecture. Or they can be used to reinforce important topics learned in class. Each study guide has fill-in-the blank style questions, and many have links to videos where similar problems are worked through. Finally, suggested practice problems relevant to the topic of each study guide are listed at the end.

This activity by Lauren Roberts guides students through the process of finding, vetting, summarizing, and citing a scientific article. Professor Roberts is from South Mountain Community College in Arizona's Maricopa Community College District.
Material Type: Activity/Lab
This brief instructor-facilitated activity asks students to observe a simple demonstration, record their observations, and apply their knowledge to other conditions. It was written by Johnathan Hugh Broome from University of Southern Mississippi.
Material Type: Activity/Lab
This activity features calculations and rankings as well as student evaluations of their understanding. Instructions are provided on the document, which is ready for distribution to students. It was developed by Celestina A. Pangan and Madhu Gyawali.
Material Type: Activity/Lab
This group activity engages students in the calculation of absorption spectra. It is appropriate for any course covering the baseline mathematical concepts of atomic spectra, including chemistry, physics, astronomy, and related courses.
Material Type: Activity/Lab
Enhanced lecture slides for Ch. 1-17 of the OpenStax Chemistry textbook. Ch. 1-6 are in their final version. Ch. 7-17 are still a rough copy, but the final versions will be uploaded as they are completed.

I've converted the collection.xml file in the zipped version of OpenStax Chemistry v 12.1 https://cnx.org/exports/85abf193-2bd2-4908-8563-90b8a7ac8df6@12.1.zip/chemistry-12.1.zip to an imsmanifest.xml file so that one can import the whole book into D2L (Brightspace). Attached here is the imsmanifest.xml file alone. I don't know a lot about IMS compliance, but I think this imsmanifest.xml file could work for other LMSs as well. Please let me know if it does, or if you have other ways of importing the textbook to a LMS. I have also "prettied up" the html files in the zipped version of OpenStax Chemistry v12.1 by: - removing the path for the images, - using <details></details> for objectives, summaries and solutions, and - creating a .css file which takes advantage of the various environments defined in the .html file That new zip file is attached. Finally, I'm also attaching the perl script that I used to change the .html files, in case you want to make systemic changes to what I did or try something else.
