• I've been working on the grades which I have received from the TAs. I do not have all of the TAs reporting yet, but of those I do have the inclusion of the Homework and Laboratory scores effect the course average. The first exam average was 53 (which is a high D). When the other grades earned to date are included the class average moves up to approximately (4 sections are not included) 61 which is right in the middle of the C range. As soon as the remaining grades are transmitted to me I will be able to post grades. This will probably be on Wednesday, October 1.
  • To estimate your current grade sum your problem set scores, your lab scores and your exam score and divide by the total possible. For an even better estimate of your grade do the following; find the percentage of your homework, laboratory and exam scores. Multiply the homework and lab scores by 0.22 and the exam score by .55 and add those three numbers together. That is the best estimate of your current grade.
  • Let's congratulate Stuart Ryder for determining the correct concentration of H2O.
  • Remember if your performance is not what you anticipated and you would like to talk to me drop by my office or see me after class to set an appointment.
  • A link to the answers to our first examination is located at the bottom of this page.
  • No more mr. niceguy...when it comes to Problem Sets. If your problem set is not turned in at the beginning of class it will NOT be accepted. No ifs, ands or buts.
  • Laboratory this week (Experiment #4: Stoichiometry of Some Reactions of Copper). There are several pre-laboratory questions which will require stoichiometry calculations. Check these over. The lecture on Friday, September 26 is important. Safety Issues: You will be working with nitric acid and sodium hydroxide. These reagents must be handle carefully! The reaction with copper metal and nitric acid MUST be performed in the hood to minimize air pollution in the laboratory. The brownish poisonous gas which is produced is not good for the lungs. Heat the solution in Step #2 slowly and carefully for best results. Do the pre-laboratory questions before coming to laboratory!!! If you do not the teaching assistants have been authorized to deduct 6 points from your final laboratory score for Experiment #4. Be sure to read your experiment before class. The experiment is long and the more you understand before beginning the experiment the more efficient you will work.
  • How do you tell if a reaction is an oxidation-reduction reaction??? If the elemental form of a substance dissappears or appears in the reaction, or there is a change in the number of oxygen atoms around another element the reaction is an oxidation-reduction reaction.
  • Return Examination Policy: Exams will be returned in laboratory next week. You will have your laboratory period to review the examination to see if any problems require re-grading. To have your examination re-graded return to your TA (not to Dr. G) while you are still in laboratory! Your exam will be check to be sure the question(s) were graded properly. Check the WEB to view the key and for comments on how exam was grade.
  • Problem Set #4 due on Wednesday, October 1st.
