All Sections:
• Start studying: Chapter 10. Quick notice: when using the gas constant, R, use only 8.3145 J/mol*K or 0.082057 L*atm/mol*K to receive full credit on problems. Other values of R will be graded down, so "use the good versions", ok? :)

This is the week of gases and intermolecular forces. One cannot understand gases without knowing the value of the universal gas constant, R (which has a value of 0.082057 L atm mol^-1 K^-1, or with different units, 8.3145 J mol^-1 K^-1 - memorize and use both values in all of your problems). If you have any questions, please let me know.

Here's what is happening in week 6 of CH 222:

• Explore the material in Chapter 10. There are several tools to help you learn the material.... they include:
  • Read Chapter 10 in the textbook
  • Watch the Complete Lectures for Chapter 10 (found here: Part I, Part II)
  • Lecture videos for Chapter 10 will be found on YouTube and as a Podcast.
  • Chapter Guide Four (online learning materials for Chapter 10) might be helpful
  • "Mini video lectures" ("Screencasts") can be found in the Videos page for CH 222 under Chapter 10.
  • The Concept Guide for Chapter 10 and other relevant handouts could prove useful.
• Due: Problem Set #4 which covers problems from Chapter 10.
  • Use this link to get the Winter 2026 version of problem set #4, and use this link to find the recitation video which you can use to self correct your work before turning it in to the instructor.
  • Practice Problem Set #4 might be of help while completing problem set #4; answers are included at the end of the document.
• This Week: Seminar Quiz #4 and the (actual) Quiz #4
  • All quizzes (Seminar Quizzes and actual Quizzes, as well as midterm exams and finals) are closed book / no notes allowed. You cannot use a cell phone or computer; you can have a dedicated calculator and a periodic table (which I will provide) only.
  • First, take Seminar Quiz #4. You will have 20-30 minutes to complete the quiz, and afterwards we will self correct the Quiz as a class before turning it in. If you are late, or do not attend recitation for any reason, your score will be a zero on the Seminar Quiz.
  • After taking the Seminar Quiz, you will take the actual Quiz #4. Quiz #4 will take about 30 minutes and consist of several 'show your work' questions. Turn in the quiz when done (I will pass back any corrected work I have for you at this time.)
  • Sample Quiz #4 (answers at the end) might be useful to help you prepare and study.
• Due: The "Chromatography " Lab
  • Bring the completed lab (the last two pages only; the PreLab and PostLab questions only) with you to recitation.
• Start: The Solids Lab.
  • Bring a printed copy of the Solids Lab with you to recitation.
  • The lab video (found here) might help you prepare for the lab.
• Due: The Rough Draft of your Class Presentation Paper.
  • A "rough draft" for this assignment means at least two typed pages with at least one science peer reviewed abstract and citation; see the FAQ for more information. Also make sure you include the completed Rough Draft cover page.
  • The Rough Draft of the Class Presentation Paper will be due in recitation.
