• My e-mail is down and has been down since Wednesday afternoon. If you have sent me a message I apologize for not answering. Drop by if you have questions.
    •
  • The ichat server is now working. I will be watching our chat room today (Thursday, April 8, 1999). So if you have questions get on. If I do not answer immediately I will eventually.
    •
  • Friday, April 9, 1999 is the last day to withdraw from classes with an automatic 'W'. After the 9th you must have a least 40% of the class for a 'W'. If you have any question about your position in the course and what you need to do please drop in and see me, or schedule an appointment.

  • I've got some updated Chapter 16 notes up now (changed Monday, April 5, 1999 at 10:30 pm).
    •
  • Finally have some sample questions for our exam. I still want to add a few more and will have those up sometime Tuesday, April 6, 1999.
    •
  • Exam III will not have any questions from Chapter 17. However, remember we had a titration laboratory and we discussed neutralization of acids and bases in Chapter 15.
    •
  • When you review the problem sets and the problems at the end of Chapter 15 and 16 in our textbook it becomes clear we have been doing LOTS of calculations! Concentrations, solution preparation, solution stoichiometry, equilibrium, solubility, etc. Sharpen up on using your calculator...remember to get comfortable with squaring, cubing and finding square roots or cube roots! The best thing to do is to practice solving problems. Check here for some more sample problems.

  • Congratulations go out to CHEM 1225 student Megan Robbins for her performance this weekend at the Texas Relays in Austin. She kicked some Texas b... by polevaulting 12 feet 3.5 inches. That's 12 FEET (3.66 meters). WOW! Way to go Megan!
    •
  • I have added some recommend problems which you should understand for our next exam. (See the Problem Set link.)
    •
  • Exam III is Thursday, April 8, 1999 at 5:30 pm in PS141.
    •

  • Check out the changes in this week's laboratory.

    •

  • 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.
