CHEM 1314 Fall 2002 Annoucements

Last updated on Monday, November 18, 2002 at 1:40 pm

I've posted an updated version of Experiment 13 that we are doing in laboratory on Monday, Tuesday and Wednesday this week. The changes are relatively minor, a few typos. The major change was adding a column to each of the tables. The new column is for bond distances.

The PLE for Monday is ready.

PS13.7 is a little funky. Here is the correct version of PS13.7.

PS13.7a. Which of the molecules list in PS13.5 above are polar and which are nonpolar? Note: exclude NO₂^-.
b) Indicate the hybridzation on the central atom for each of molecules in Problem 13.5 above.

Since I was unable to videotape Friday's lecture I have reviewed my lectures from CHEM 1314 Fall 2000. There is a lecture on an introduction to VSEPR. Also PS13 has a question on formal charge, which I have not discussed in class. Check your text, or check out the lecture below.

Lecture, Wednesday, December 4, 2000:VSEPR stuff

Lecture, Wednesday, November 29, 2000: Formal charge

Lecture, Wednesday, November 22, 2000: Bond energy

Check the laboratory link for what is happening in laboratory the week of November 18, 2002. Students in sections 19 - 25 and 28 will meet in CLB406 to do a chemistry activity on the computer.

Exam III Average is 56. You continue to do better! Lindsay Breece scored a 93 for the high on the exam! WAY TO GO LINDSAY! SWAG on Friday!

Curious about the chemistry associated with the colors of leaves this time of year? Check out Dr. Shakhashiri's 'Chemical of the Week' web site.

The current class average is 62.6%. This is very good. The best class average is 65%.

IMPORTANT: Here are the room assignments for the hour exams. The first hour exam is scheduled for Wednesday, September 11, 2002. The exam begins at 5:30 pm and ends at 6:25 pm.

Check out the link to the web site for our textbook (BLB). The link is near the top of the left frame on our web site. Clicking on the link will take you to a page with an image of our textbook. Near the top of the page is a dropdown menu listing the Chapters in the text. Select a chapter and a page will be loaded for that chapter that contains links to resources. If you would like some practice problems try the Problem Soving Center. When the Problem Center page is load scroll down to the red button under flexible questions. Select the Homework link. This will generate a set of questions from the chapter. You will need a calculator.

I've added a link to the Brown/LeMay/Bursten Web Site run by Prentice-Hall. There are multiple choice 'quizzes' there that you can take to see how well you understand many of the concepts we have covered in Chapter 1. You should also not that at least one of the movies we viewed in class on Wednesday was from this site. That movie (the reaction of iron and sulfur) is also located on the CD that came in your textbook. There are some additional resources at the web site and on the CD that you may find useful.

So our first lecture down. As you can see I did not cover everything in class that were in the lecture notes. That is likely to continue to happen. I will still hold you responsible for the material in the lecture notes. If you have questions over content covered in the lecture notes that I did not (or you think I'd not) cover during lecture you are welcome to drop by and visit me or send an e-mail. Sometimes I will discuss the missed material in the next lecture, sometimes I'll simply tell you to review the material in the notes and the textbook and see me if you have questions.

I've set my office hours for this semester for 1:00 pm - 2:30 pm M, W and F. Also, if my door is open you are welcome to walk in and ask a question. I will also make appointments.

Here is a very nice Periodic Table that contains lots of physical properties and chemical properties for the elements.

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.

Be sure to bring your textbook and a calculator to laboratory this week! Yes! Labs are meeting this week.

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;
