PLE#21 is ready. There is a QuickTime movie in this PLE that you must watch to answer some of the questions. The computers on the 4th floor in the Classroom Building can play QT movies. The Library computers CAN NOT.

Useful heats of formation (H˚_f) for PS#8:

HELP Sessions!

• Sunday, October 12, 2003 at 7:00 pm in PS141. Enter the building from the doors facing west (nearest my office).
• Monday, October 13, 2003 at 7:30 pm in PS141...Exam 2 help.
• Gary Swantner and Danny Holderman are doing a Review Session in preparation for Exam II on Tuesday, October 14th from 5:00 - 6:00 pm in ES317 (our classroom). Students not in Gary or Danny's sections are welcome.
  

You have been using PLEs and ICEs this semester and I would like to get some feedback from you. Please answer the questions on the PLE Mid-Semester Survey located on your personal page (the main page that comes up when you go to your personal page). Completing this survey will be worth one ICE (4 ICE's = 1 PS). Thank you in advance for your comments.

PS#8 is ready. Remember it is due Monday, October 13, 2003. So we will need a HELP Session on Sunday, October 12th. Corrections on PS#8 so far;

• PS8.4...the 2nd equation has a coefficient for methane that is wrong, instead of 2 it should be 1...the correct equation is;
  CH₄(g) + 2O₂(g) ^__> CO₂(g) + 2H₂O(g)
  Note: if you have not printed your PS8 yet, this error has been fixed on your PS.
• PS8.5....the third equation the oxygen molecule has the wrong coefficient...the correct equation should be,
  4NH₃(g) + 3O₂(g) ^__> 2N₂(g) + 6H₂O(l)
• In PS8.1 if you have CO₂(g) ^__> CO₂(g) change the equation to CO₂(g) ^__> CO₂(s).
• In PS8.7 if your equation is; 4C₂H₅NO₂(l) + 9O₂(g) ^__> 8CO₂(g) + 10H₂O(l) + 2H₂(g) change the product from 2H₂(g) to 2N₂(g).
  

The most current grades are posted for all TA's. Remember if any PS or lab score does not agree with your score on the PS or lab talk to your TA. If you do not see a change in a reasonable length of time (a week) please let Dr. G know.

Hey, anyone out there want to win an iPod?..the way cool mp3 player by Apple. This opportunity is only available to OSU students. Check out the web site with the information. If anyone has questions get in touch with me, and let me know if you are interested I may be able to help. I just got this information this afternoon, so get over to the SU Bookstore and Kara in the back of the store.

Lab information for this week is available at your personal assignment page. Students in Section 10 - 15 and 19 need to do the onLine PLabE (pre-laboratory questions) before going to laboratory. All other sections should complete the pre-lab questions in the laboratory manual.

Found in ES317 after class on Wednesday, September 24th: 1 calculator, 1 pair of sun glasses and 1 carabiener. Claim in my office.

With 10 sections entered the exam average is 56 and the high score is a 98. You will get your exams back in laboratory beginning Thursday, September 11th. When your TA returns your exam look it over. If you have any questions and would like us to re-grade a question on your exam write a brief note and return the exam to your TA. We will look at the exam in our next staff meeting. If you are satisfied with your exam you may keep it. After you take the exam from your lab room I will NOT change the grade!

Be sure to check what you must complete BEFORE attending laboratory this week. Go to your Assignment Page.

Your TA's e-mail address is below.
