• For next weeks laboratory (Experiment #9: Models and Molecules) you are to bring your textbook to laboratory. Be sure you understand the following concepts; valence electrons, Lewis structures (we'll do today), octet rule, exceptions to the octet rule, formal charge.

  • Problem Set #10 comments: in PS10.5 assume each substance is pure and in its standard state phase; in PS10.9 you are expected to indicate the formal charge on each atom in each resonance hybrid. When asked to indicate formal charge that implies on each atom.

  • Here is a site which shows static images of the orbital shapes we discussed in class and viewed using the CD-ROM. http://yip5.chem.wfu.edu/yip/organic/pchem-atoms.html (JPEG images of orbitals)


    ES317 will NOT be available for Exam III so new rooms have been obtained. James Graham's and Andrea King's students are not effected by this change.

  • There will be a HELP Session on Thursday, November 13, 1997 at 3:30 p.m. in PS141. If you have questions over the next problem set or the sample Exam III please attend.

  • The animations which I have been using in class for Chapter 7 can be accessed via this link.

  • Reminder about PARTS THREE and FOUR in Experiment #7: CONDUCTIVITY: I have told the TAs to announce in laboratory that I expect students to write the formulas (with charge) of all the ions (both cation and anion) that are present in solutions which are identified as strong or weak electrolytes. Clearly there are no ions in the nonelectrolytes, but the strong electrolytes are primarily ions and the weak electrolytes are 3 to 7% ions. You are expected to include in the Tables for PART THREE and FOUR the formulas of those ions which are in the solution you tested. If you have any questions about what is expected contact your TA or me.

  • We have Justin Brooks to thank for generating an Excel spreadsheet which will calculate your current course grade. You enter in your homework, laboratory and exam scores and it will calculate your actual course percent. Just follow the simple instructions. If you have questions send Justin or myself a message. WAY TO GO JUSTIN!

  • OK, the latest rumor is either Dr. Gelder or Dr. Purdie will be teaching CHEM 1515.02 next Spring. The final decision of who teaches the section will depend on other factors within the department.

  • I've also added the Exam II KEY for your notes.

  • This space reserved for the link to all of your grades. The scores are sorted by your SIC#.

    Want your SIC#?? better see or e-mail dr. g.

  • While surfing I found this site for information on medical careers. You may have this information already, but I found it interesting.
