  • Most current grades that I have are now posted.
  • Answers to Exam III are now available.
  • I've put some suggested problems at the end of Chapter 18 and 19 at the Problem Set link. Check them out.
  • On the final I've recommended students review exams I, II and III to be sure you understand problems you did not do well on. There will also be an integrated rate law problem on the final. I was not able to ask one on the third exam so I decided to include one on the final.
  • Answers to PS14 are posted.
  • Our Exam I, II and III are posted at the Exams link. Right now they are blank exams. Answers to exam I are now available. Still working on the others.
  • Here are latest grades along with a prediction of what you must do on Exam IV and the Final for a particular grade. Please note I've not received grades from a few TA's yet. As I receive them I will post more grades.
  • HELP Sessions!

  • Here is a nice table of Ka's and Kb's for you. It has C2H5NH2 also.
  • I want to make an important point about the use of graphing calculators on CHEM 1515 exams. You ar enot to store mathematical equations/definitions in memory on your calculators. If you do, it is called CHEATING (Academic Misconduct). On Exam III you may use the solver to do a quadratic equation, but that is the only exception I will allow. Otherwise all you are using on your calculator are the function (+, -, x, /, e, ln, log, 1/x, etc.). If you have ANY questions about this policy please drop by and talk to me.
  • Dr. Rockley has reminded me of a web site that he has developed that randomly generates problems (with answers) of the type that might occur on an examination. Check this site out and try some of the problems. (Note: I saw a problem calculating the fraction of particles with an energy equal or great than the activiation energy. We did not do a problem of that type so do not concern yourself about answering.)
  • Dr. Rockley also referred to some notes he has on the web for his discussion on equilibria. Check those notes out.
  • The TA's e-mail addresses are;

    • Nellie Bruce: brucen@okstate.edu
    Bill Alley: billalley@hotmail.com
    Randy Hallford: random30_99@yahoo.com
    Melissa Caldwell: mcaldwe@okstate.edu

  • Want some EXTRA CREDIT? Complete the form at the SID#/Name link.
  • Be sure to bring your textbook and a calculator to laboratory the first week of classes. Yes, the CHEM 1515 laboratory does meet this week (January 16 - 19). (See the CHEM 1515 Syllabus)
  • Sitting around with nothing to do? We are going to begin lecture on Wednesday, January 17th discussing Chapter 11 in Silberberg. I recommend you review Chapters 9 and 10 before class. In particular, refresh your recall of drawing Lewis structures, the concept of electronegativity, ionic and covalent bonds, bond polarity, molecular polarity, molecular shape (in particular central atoms with 2, 3 and 4 groups of electrons). Check out lecture notes from CHEM 1314. In particular look at;

    • Lecture Notes for Friday, November 17, 2000 and Monday, November 20, 2000: Ionic compounds.

    Lecture Notes for Monday, November 20, 2000: Covalent compounds and electronegativity.

    Lecture Notes for Monday, November 27, 2000: Lewis structures.

    Lecture Notes for Wednesday, December 6, 2000: Valence Shell Electron-Pair Repulsion.
