Finals week is right around the corner - ack! - but this also means that the winter break is coming quickly - I guess they even out somehow... ;-)

This week we will be exploring spectroscopy, the study of electromagnetic radiation (i.e. light) when it interacts with matter. This is a fascinating field with lots of implications for not only chemistry but the world in general... and it is one of my favorite chapters. Some/most of this material might be new to you, so spend some time watching the videos, reading the textbook, etc... and let me know if you have any questions!

Here's what is happening in week 11 of CH 221:

  • Explore the material in Chapter 6. There are several tools to help you learn the material.... they include:
  • Due: Problem Set #6 which covers problems from Chapter 6.
  • This Week: Quiz #6
    • Section 01 and Section H1 will take the quiz in class during recitation in AC 2501.
    • Section W1 will receive a link to the quiz via email Wednesday evening. The quiz should be emailed to the instructor.
    • Sample Quiz #6 (answers) might be helpful.
  • Due:: The "Atomic Spectrum of Hydrogen" Lab.
    • Section 01 and Section H1: The "Hydrogen Spectrum (in class)" Lab is due at the end of lab during your lab period (ie by 5 PM on lab day.) Make sure you bring a printed copy with you to lab this week, it will be considered late if you turn it in after lab is done. Also bring your calculator with you to this lab.
    • Section W1: The "Hydrogen Spectrum (online)" Lab is due via email on Wednesday, December 6 by 11:59 PM.
  • All extra credit closes Friday, December 8 at 9 AM.

Here's a preview of what's going to be happening during Week #12 - Finals Week:

There are three assignments due during finals week. There will be no extensions for late work, so make sure you turn your material in by the posted due date for your lab section. Please be aware: I do not return final exams to students. You will be able to see your final grades soon after the Wednesday deadline but not your graded assignments, and your final grade in the class will be available by 5 PM Friday. The three assignments are:

  • The Lab Final
    • The Lab Final will be a Take Home Lab Final that consists of six "show your work" problems relating to the various labs we have completed this term.
    • Showing your work on these problems is critical! Be clear in your steps, circle final answers, etc.
    • Use your old lab reports to help conquer the questions in the Lab Final.
    • The Lab Final will be available by 8 AM Monday, December 11 via an email link (check your email!)
    • Section 01 and Section H1 will turn in the Lab Final at the time of their Lecture Final on Wednesday (see below.) Printed copies only will be accepted for Section 01 and Section H1 (no emailed versions.) Late submissions will get a score of zero, no exceptions.
    • Section W1 will email the Lab Final by 11:59 PM Wednesday, December 13. Late submissions will get a score of zero, no exceptions.
  • The Final Exam Prep worksheet
    • The Final Exam Prep is similar to the other Exam Prep Worksheets... it is a handout designed to help you get ready for the lecture final exam. I will not be able to help you with the final exams this week, but I can help you with the Final Exam Prep!
    • Section 01 and Section H1 will turn in the Final Exam Prep worksheet at the time of their Lecture Final on Wednesday (see below.) Printed copies only, no emailed versions, and late submissions will get a score of zero.

    • The Lecture Final is worth a total of 180 points; 160 of the points will be from the 32 multiple-choice questions and the other 20 points from the short answer questions.
