Assignment for 12/6/07

To my students:

Living Environment 1:
• HW #26 (Due Monday) - Glencoe: Read pp. 228-233, Do p. 233 Problems #1, 2, 4.
• PD 8 students: As I mentioned, you will be responsible for covering the subject of photosyntheis reactions on your own (include light-dependent phase and Calvin cycle); as you have made your choice, so I won't be going over the subject in class.

Regent Chemistry 1: I am fairly disappointed, to say the least. Same questions of similar types have been answered more than 3 or 4 times during today's review; it's clear that you have not taken advantage of the review sheet or pay attention during the session, which then means the review sheet/session have outstayed its usefullness... Exam will be on tomorrow.

Below, I am including the answers to the questions which we have not gone over in class:
4. c) Ag2SO4 - Silver sulfate
d) Cu3N2 - Copper (II) nitride
e) FeS - Iron (II) sulfide
f) Mg(NO2)2 - magnesium nitrite
5. a) non-polar covalent

6. a) non-polar molecule
