  • Hannah Holleman was kind enough to share her notes from the Help Session on Wednesday evening, October 8, 1997. If you were unable to make the Help Session check out the notes.
  • I was looking for some links for our class on calorimetry and came across a homepage for CHEM5 which looks to be a chemistry course similar to ours offered at Harvard. There is a link to some sample exams from the homepage. The exams are pdf files so you will need the Acrobat Reader to view them. Checkout what Harvard's introductory exams are like.
  • Laboratory next week (Experiment #6: Heat of Neutralization). There is a correction on the Pre-Laboratory Questions problem #4. In order to do the problem you need to know there are 1.50 kg of water in the calorimeter. You must be careful with the NaOH pellets. DO NOT touch these pellets with any body parts! Do not allow these pellets to touch the balance pan either.
  • 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!
  • 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.)
  • Here are suggested problems from Chapter 4 in your text; 4.3, 45, 4.7, 4.9, 4.11, 4.13, 4.17, 4.19, 4.21, 4.23, 4.25, 4.29, 4.31, 4.35, 4.37, 4.39, 4.45, 4.47, 4.49, . 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!
