  • PS16 is available.
  • Here are some clips that may be helpful as you are working on PS14.
  • Here is some discussion and help on PS14.1 from the Help Session on Monday, November 27, 2000

    Here is some discussion and help on PS14.3a and PS14.3b from the Help Session on Monday, November 27, 2000. (Note: Check lecture notes on Monday, November 13, 2000 for an explanation for PS14.3c.)

    Here is some discussion and help on PS14.6 (lattice energy) from the Help Session on Monday, November 27, 2000. (Note: The tape ran out as I was completing this problem, so check the lecture notes from Monday, November 13, 2000. There is a discussion of lattice energy and there is a MacroMedia Director animation that shows the trend for the compounds listed in this problem. You'll need the Shockwave Plug-in to view the animation.)

    Here is some discussion and help on PS14.7b from the Help Session on Monday, November 27, 2000

  • Here are some clips that may be helpful as you are working on PS15.
  • Here is some discussion and help on PS15.1 from the Help Session on Monday, November 27, 2000. (Note it may also be useful to look at the clip for PS14.9 and look at the lecture notes on the Born Haber cycle that I have put up.)

    Here is some discussion and help on PS15.3 from the Help Session on Monday, November 27, 2000. (Note: Here is a clip from lecture on Wednesday, November 22, 2000 where I introduce the concept of polar covalent bonds and nonpolar covalent bonds.)

    Here is some discussion and help on PS15.4 from the Help Session on Monday, November 27, 2000.

    Here is some discussion and help on PS15.5 from the Help Session on Monday, November 27, 2000. (Note: This problem is similar to a problem we did in PS12.)

    Here is some discussion and help on PS15.6 from the Help Session on Monday, November 27, 2000. (Note: In this discussion I cover part i and j and discuss multiple bonds in Lewis structures.)

  • Here are some lecture notes on ionic bond, Born Haber cycle and lattice energy. Some lecture notes on covalent compounds and electronegativity and some lecture notes on doing Lewis structures.
  • Remember you must do the pre-laboratory questions BEFORE arriving in laboratory this week. For those students in the 1:30 pm lecture section go to the laboratory link and print out the first two pages of the laboratory experiment. They are very easy so do them.
  • Grades are up with a prediction for Exam IV and the Final. The first page you will go to explains in some detail how the numbers are determined and how to interpret them. It is up to you whether you read this information. However, I provide this as part of what I do for you. I can make mistakes in the calculations, although I've double checked all the calculations. I've provided a description on how to calculate the numbers I've calculated for the prediction. It is your reposnibility to check those calculations before you make any decisions regarding Exam IV and the Final. If you have any questions check with me! Go here for grades.
  • This week everyone will be doing Experiment 12 Molecular Architecture. If you are in the 1:30 pm section you will need a copy of this experiment. They will be available in laboratory, but if you would like your copy early to review get it here. You should be able to do the Pre-Lab Questions 1 and 2. Question 3 is a little more difficult. Give it a try.
  • I hope everyone had a relaxing, pleasant break. NOW BACK TO WORK! :) Looking forward to seeing everyone in class on Monday. Lewis structures here we come!
  • PS15 is available.
  • Here are some corrections to the original PS14 distributed in class. The current version of PS14 that is downloaded now is the corrected copy. PS14.1d should read 'an electron in the 2nd shell in Ca'; the other typo's are minor, PS14.3 has three part a's rather than part a, b and c; there may be some extra PS14.5's. Only PS14.1d is critical.
  • Did someone leave a copy of Silberberg in their exam room last Wednesday evening? Drop by, identify the room and the book.
  • If there are any students who are not going home for Thanksgiving please get in touch with Dr. G. by Wednesday afternoon. Marcellus Randall, one of our CHEM 1314 students, and his family welcome anyone who would like to share the Thanksgiving meal.
  • New grades are now posted. Even though the Exam III average is lower than I expected the overall class average is still 71%.
  • I've entered the exam scores for eighteen sections as of midnight. The average for these sections is 59. The high score so far is a 95. Congratulations go to Amy Fesler (a repeat) and Luke Smith who received the highest grades this time. Lots of swag on Friday plus something new...a minimol.
  • Check out what's up in laboratory this week.

  • ----Previous Announcements----

     

  • Here is an interesting site which has some photographs of a human, a cat and a view of downtown Seattle taken with an infrared camera...cool!
  • Here is an interview with Douglas Haynes. The first Pistol Pete Pizza Olympic Champion.
  • 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.
  • We have a winner. Douglas Haynes from the 3:30 pm section is the new Pistol Pete Pizza Champion Pizza Competitor Winner. Based on his time in three challenging events Douglas beat out a large super size group of challengers to end up as the BIG KaHoona. Douglas won a new television (lets all go to Douglas' to what the World Series...who'll bring the pizza?) plus a very cool medal. We'll try to get some video and possibly an on camera interview of the world champion...possibly even showing how he prepared for the grueling events.
  • Here is video announcing the high score for exam 2 in the 1:30 pm section and the 3:30 pm section.
  • 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.
  • 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.
