Section 1: Under 'Homework Documents' you will see two items; one is a video that I made for you and the other is a pdf file of a blank periodic table. The video is a swf. file, which means you need Adobe Flash to watch it, if you have an older computer you can just watch it in Internet Explorer, or you can download a swf opener (just google swf file opener and you should find several options).
Watch the video and then fill in the periodic table with the electron configurations blocked out for each section. You should also color code it. There is an example image in the video.
Also, in your notebook, write out the electron configuration for Lithium, Barium and Phosphorus. Don't worry about making a mistake - we will go over it tomorrow in class.

Thank You!
Gents-
Thank you so much for your generosity towards our 'T-giving $' fund. I was able to use the $57 in cash to buy 12 cartons of shelf stable milk, 10 can of chicken broth and 2 cans of canned fruit. I also donated over $10 in coins to the Campus Ministry office to help them fund service trips! I am so proud to be the teacher of such generous young men...way to go!

Contemporary Chemistry Discussions
All: Our first discussion will take place tomorrow morning at 7:45 in room 3K3. Articles about this week's topic can be found at the bottom of the page, to the right of the powerpoint. Please feel free to look up/bring in other articles on the same topic. ALL future info about these discussions will be posted there.
See you in the morning!
See you in the morning!

Section 2: Your quiz corrections are due on Monday. Also, here is a link with the answers to the problems you started today in class. Enjoy!
Molecular Formula Calculations
Molecular Formula Calculations
Wednesday, November 2
All Sections: Complete the following problems in your notebook:
1. A compound contains 36.48% Na, 25.41% S, and 38.11% O. Find its empirical formula.
2. Find the empirical formula of a compound that contains 53.7% iron and 46.30% sulfur.
3. (This one is tricky tricky but you can do it! Remember that you need your percentages to add up to 100 - and you CAN get that with the information given. Don't forget what you know about mole calculations and kick this problems butt!)
A compound containing sodium, chlorine, and oxygen is 25.42% sodium by mass. A 3.25 g sample give 4.33 x 10^22 atoms of oxygen. What is the empirical formula?
