• ### Laboratory this 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.

• 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!
