• Who is going to be the first student to e-mail me their completed Problem Set! Two former students are standing in my office asking me if anyone has e-mailed me their PS and I said no, not yet!
  • If you are in laboratory section 33 (Ludy) a student's textbook is missing. Possibly another student picked up Eric's book by mistake, thinking it was their own. If you would check the first page of the text Eric has written his initials inside 'E.B.' Let me know.
  • Exam #2 is Thursday, October 23rd at 5:30 p.m. in the same rooms as the first examination. IMPORTANT NOTE: The 23rd is Thursday of the week of Fall Break!!! Be careful.
  • If you would like me to post all of your scores (homework, laboratory and exams) using a SECRET IDENTIFICATION NUMBER which only you will know you must e-mail me requesting your secret number. I will reply with a message to you with that number. Keep that number secure from all living people!
  • At least one of the TAs has been in to say the scores on PS#4 are nothing to write home about!! We may need a HELP Session next week on stoichiometry and limiting reagents. Lets go for Wednesday, October 8th, PS141 at 7:30 p.m. You bring the problems and we'll work them out!
  • Here are suggested problems from Chapter 3 in your text; 3.55, 3.57, 3.59, 3.61, 3.65, 3.67, 3.69, 3.71, and 3.73. You do not have to turn these problems in, but you should look at them as part of your preparation for Exam #2 (Thursday, October 23rd.)

  • If at anytime during the semester you show up for laboratory and the TA does not. You do not leave until told to leave by Dr. Cruz or myself. You are to contact Dr. Cruz (PS243) or me as soon as it is evident the TA is AWOL.
  • If you have a WEB page which you would like to share click here to contact the StudentWEBMASTER.
  • 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.
    • Check out the sample calculation for Joe Student on how to determine your percentage in the class. This is just a '.gif' of the calculation.
    • If you would like an Excel file which will do the calculation automatically select one below. (NOTE: Let me know if you have any problems with the Excel file.) I have binhexed the 'xls' version of the file. Hopefully your browser can debinhex this file.
    • Here is a JavaScript which will calculate your future examination scores for a particular grade. Check it out!
  • Laboratory next week (Experiment #11: Quantitative Determination of Phosphorus in Plant Food). There is a change in the laboratory procedure. On p. 11-5 it tells you to dry the precipitate on a paper towel under a heat lamp, scrape the dried precipitate into a tared dish and weigh. Instead, you should pre-weigh both a piece of filter paper and a watch glass. Then you can place the precipitate and filter paper on the watch glass and dry them under the heat lamp, cool and weigh.
  • 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.
  • 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.
  • 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 #5 due on Wednesday, October 8th at the beginning of class.
