  • Anyone else having trouble with the video clips from the Help Session? Send me an e-mail and let me know what is happening if it is not working well for you. The problem is the server is getting hit VERY heavy tonight...lots of you working on the PS.
  • To do PS10.7 you'll need some additional information that is not in your textbook. The specific heat of H20(s) is 2.09 J·g-1C-1 and H20(g) is 1.84 J·g-1C-1. The enthalpy of fusion for H20(s) is 0.334 kJ·g -1 and the enthalpy of vaporization for H20(g) is 2.26 kJ·g-1. Here is a sample problem like PS10.7 and 10.8 that I did at the Help Session Monday evening.

    • Here is an html sample problem like PS10.7 and PS10.8. (The video server is getting overwhelmed tonight. It can not keep up with the demand!)

    Here is an html sample problem like PS10.5 and PS10.6. (The video server is getting overwhelmed tonight. It can not keep up with the demand!)

  • Here are some additional specific heats that may be helpful for PS10.

  • PS11 is available at the Problem Set link.
  • Here are some clips from Friday, October 20, 2000 lecture that are similar to problems on PS10.
    •

    Here is discussion which should help in PS10.2 from the Help Session on Monday, October 23, 2000.

    Here is an example of a problem like PS10.4 from the Lecture on Wednesday, October 18, 2000.

    Here is discussion which should help in PS10.5 and PS10.6 from lecture on Friday, October 20, 2000.

    Here is an example of a problem like PS10.5 and 10.6 from the Help Session on Monday, October 23, 2000. (Note: Since we were not in PS141 the audio is a little low, so listen carefully.)

    Here is an example of a problem like PS10.7 and 10.8 from the Help Session on Monday, October 23, 2000. (Note: Since we were not in PS141 the audio is a little low, so listen carefully.)

    Here is an example of a problem like PS10.9 from the Lecture on Friday, October 20, 2000.

    Here is an example of a problem like PS10.9 from the Help Session on Monday, October 23, 2000.

    Here is an second example of a problem like PS10.9 from the Lecture on Friday, October 20, 2000. (I did not do this example in the 1:30 pm lecture section.)

    Here is an example of a problem like PS10.10 from the Lecture on Friday, October 20, 2000. (I did not do this example in the 3:30 pm lecture section.)

  • Here is video announcing the high score for exam 2 in the 1:30 pm section and the 3:30 pm section.
  • Check out the laboratory information for this week at the laboratory link.
  • If anyone would like to talk to me about their grade on the exam or in the course you are welcome to drop by and we can talk. Call ahead or check the Webcam to be sure I'm in the office.
  • GRADES are up...it is late, so hopefully I've not made any serious errors in my calculations. I'll double check everything in the morning. Overall average is still good!
  • Looks like the class average is 61. Not terrible, not fantastic, OK.
  • There was a perfect score (at least one so far)...Chris Smith from the 1:30 pm section got a perfect paper!!!! FREE LUNCH WITH DR. G. (Calm down Chris!) CONGRATULATIONS! I'll have more info for everyone shortly!
  • The high in the 3:30 section was John Stewart with a 96. CONGRATULATIONS...lots of schwag on Friday!
  • If you are using a 56K modem to connect to our Web Site here is a digital lecture from September 18, 2000 which I have compressed for play at that speed. Check it out and let me know what you think.
  • I've added some sample Real audio files of some sample stoichiometry and sample limiting reagent problems at the Real Audio/Video link. You must have the Real Player (different from the QuickTime Player) to view/listen to these files. Check it out.

  • The exam average 67. FANTASTIC! I was shooting for a 65! The highest exam in each section is a 97. OUTSTANDING! Come to class on Friday and see all the swag the student with the highest grade receives!
  • Kelly Ganzel left his chemistry textbook in the B023 (Chemistry resource Center) around 4:00 pm on Tuesday. Did anyone pick up his book thinking it was their own? Do you now have two books when you thought you only should have one? Contact dr. g.
  • If you are in the 3:30 pm lecture section and have not yet located a laboratory manual you can go to the BookTrader on Hall of Fame, east of Duck on the north side of the road. They were contacted this morning and they still have lab manuals.
  • I've listed the room each section will take their exams this semester at the Exams link. Check it out. If you arrive late to the exam because you get lost and can not find the correct room I am under no oligation to give you the same amount of time to do the exam as those students who arrived on time. (Not that this will be a problem!)
  • Some new stuff to memorize
    •

    Tables 2.3 (p 67), 2.4 (p 69), 2.5 (p 69) and 2.7 (p 73). I'll give you some tricks to make Tables 2.3 and 2.4 real easy to remember, but Table 2.5 and 2.7 have to be memorized. I promise the first exam will have some nomenclature questions.

  • Here is an example of just one of the talents of Robert Sleezer, one of our CHEM 1314 student. If you have a skill that needs to be shared with the world on video, see dr. g.
  • I just had a talk with the Director of the General Chemistry Laboratories and it was agreed that ALL students must wear eye protection in the laboratories. So all students, including HBL, must get eye protection.
  • The tutoring schedule is now available at the Tutoring link. The TA's in red are CHEM 1314 TA's.
  • I've got an initial version of a digital lecture on Wednesday, August 23rd on the QuickTime/Real Lectures link so check it out. Send me an email and let me know what happens or if you have any problems. Welcome to the future!
  • I've listed some recommended problems from Chapters 1 and 2. The list can be found in the Problem Set link at the bottom of the page.
  • If you would like to practice and test your knowledge on significant figures here is some software which will randomly generate questions. There are more of these types of randomly generated questions at our Problem Set link. Just scroll down the page a little to get to the link.
  • In order to post grade information (scores on problem sets, laboratory's and exams) I need your permission. Go the SID#/Name link and enter a number, name or combination unique to you. I will post grade information using your SID# or SIDName. You do not HAVE to have an SID#/Name if you do not want to. There are some additional questions that I would like you to answer for some EXTRA CREDIT.
  • One of the more popular periodic tables on the web is at http://www.shef.ac.uk/~chem/web-elements/. Check out if you need to find some physical properties for any particular elements.
  • Start memorizing..avoid the rush!
  • Things to memorize;

    names and symbols of the first 20 elements and 20 common elements;
    the formula and phase of all of the elements in the periodic table;
    the common prefixes for SI units;
    .

  • Need some extra money? Love computers and like to do Web stuff? Anyone looking for some parttime work writing HTML for a campus project? Check with Dr. G or see Steve Hall in LSE208. You will need to have a resume describing your work/computer experience.
  • I've generated a short Self-Test which has a few questions to provide me with some feedback as to how much you might recall from your past chemistry experience. The Self-Test has six questions. It is not graded, I'd just like to get some information prior to Wednesday's class. Give it a try, see what you can remember. Go to the Self-Test link in the left frame.
