Tetra hedral angle

Here is a link describing the tetrahedral angle (109.47 degrees). While the proof is not listed, it has a good summary of the properties of the tetrahedron. http://en.wikipedia.org/wiki/Tetrahedron

Attention Chem C111 Students: There will be a required lecture this saturday October 31st starting at 9 am. We will cover chapter 9--chapter 8 having been covered on Friday the 30th (chapters corrected) . There will be time after the lecture--about 2 hours to work in the lab.

Organic Students: The lab will be open to you this Saturday from 9 am to 2 pm.

Please show up on time. As the building is locked I have to escort everyone to and from class.

I reserved the right to not let you in if you are late.

Chem C101 Test is November 9th
Chem C111 Test is November 13th
Chem C221 Test is November 13th.

Review Session is Saturday November 7th from 8 am to 1 pm.

Chem C221: Please make sure to bring your model kits for the next few weeks.

Things to note for this week.

Chem C111 will have a mandatory make up this Saturday October 31st from 9 am to 2 pm; we will be covering Chapter 9 (Chapter 8 will have been covered on Friday the 30th). There may be some time on Saturday for Lab work.

All classes: Please make sure you are up-to-date on all your homework and lab assignments. Some students are way behind on Homework and labs, and while there are substantial deductions for late work it sure beats a zero on the assignment.

A Demonstration is planned for the 4th of November around 6:37 pm outside on the dirt south of the parking lot. Goggles will be required. I will be setting up a thermite demonstration on an aluminim block engine.

There have been a couple of confirmed cases of H1N1 flu in town. Most recently, an instructor at Cerro Coso has been diagnosed with seasonal flu (not H1N1). Wash your hands fequently


The best information about the swine flue can be found at http://www.cdc.gov/h1n1flu/ and I will be speaking to our local microbiologist (the smartest person I know) later today. Remember you do not get very good information from the popular media.

We will have class as scheduled

We will have an extra lab session this Saturday October 24th in MB 328

We will have a mandatory make up session for Chem C111 on Saturday October 31st in MB 328

We will have a review for the second midterm Saturday November 7th in MB 328

Organicers: I have 2 chromatography columns. The purpose of the lab is to demonstrate an absolute hatred for column chromatography, even though it is a powerful and useful separation technique. The 10th lab experiment will most likely be the nitration of methyl benzoate.

All Chemistry Classes: The next exam is coming up. It will be either the week of November 2nd or November 9th. A formal announcement and specific date will be set by this friday.
