Chemblog!

I posted a TON of extra help files to guide you through your Christmas break assignment; use them as needed over the next week and before the next exam. You now have literally hundreds of practice problems with extensive solutions and explanations! Take advantage of this wealth of information. We will not be spending much time in class reviewing the material that you did over this break; however, you will be thoroughly tested on the material from the break so make sure that your independent study is intensive. Send me an email if you have any problems with the topics. I also posted the gas labs. The lab write-ups are due on Jan. 8 ; the data is supplied (copy the data into your lab notebook).

I'd like to thank the awesome AP class for giving me a Christmas present: on your Bonding II exams, almost all of your work on the extensive charts on the many variations of molecules and ions ( AX3, AX4E, AX2E3, etc) was perfect! Regarding these molecular geometry charts, I have never seen such a level of unanimously excellent work from any past AP class. I know that the expertise that I witnessed did not happen without A LOT of practice, which is the key to success in this course. So, congratulations and kudos to you all! On the AP Chem exam, the bonding/molecular geometry question should be a cakewalk for you all.
