• PS8 is now available. On PS8.3 please report your answer in molarity.
  • Exam II average is 47. Looks like the exam was a little tougher than our first exam. Most up to date grades are available. Do not panic. Overall class average is 63% which is still good.
  • Check out the changes in this week's laboratory.

  • I need some volunteers to check some of the digital files I have been working on this past week. Send me an e-mail if you are interested and we'll discuss what is involved.

  • Be sure to read the laboratory for this week BEFORE coming to laboratory. The TA's have expressed some concern about whether students are reading the laboratory before lab. Remember the TA can administer a pre-laboratory quiz to see if you know your stuff!


  • Announcements from previous days

  • For predicting the products of chemical reactions (remember this is one of my favorite types of questions) I recommend you review the following notes from CHEM 1215;

    Chapter 7 notes

    Summarizing chemical equations notes

    You may also find some useful information in Chapter 6 notes

  • Some concern about the the availability of the answers to the PS has been expressed. I've checked the link and everything is working correctly from my computers. If you are having difficulty downloading the answers to the PS contact me. It should work...if it does not there is something the matter with the computer system you are using.

  • Still plenty of time to enjoy some 'fun', try the Take a Quiz link. I am not grading this so take it to see what you understand from the first two lectures. Make a note of the questions you answered correctly and incorrectly. Drop by my office if you have any questions. Let me know if you like this, we may do it again.

  • If you had CHEM 1215 with me last semester and you would like your Exam IV and Final Exam, just drop by my office.

  • Remember CHEM 1225 is a 2nd semester chemistry course. It is assumed that you have had CHEM 1215 or equivalent. If you have questions about your chemistry background drop by my office and we can talk. BTW I have a meeting at 10:00 a.m. on Wednesday, January 13, and will not be able to hold my office hours at that time.

  • The first two weeks of laboratory will spend time on a review problem set and Exercise 1, 2 and 3 in the CHEM 1225 Lab Manual. If you have Monday lab...DO NOT MISS IT!!

  • This semester I've added a new link called 'What's Important'. In this section I will discuss the important concepts in a chapter and try to relate the concepts covered in the chapter. I'll also try to provide some 'reasons' why you might want to learn this material.
