Unfortunately, my SD card ran out of memory and it missed the last 20 minutes or so.

11/18 Chemistry update and homework due 12/2
Hi folks,
Just a reminder, no class next week due to Thanksgiving. May all your turkeys be chemically tasty!
Today we began our study on the periodic table and the elements. We took a brief but, hopefully, fascinating look at how bizarre the atom really is. Next week we'll get more into detail about the atom and the elements.
Homework due 12/2 is to:
Read the text from 89 - 92
Do Review questions pg 95 #'s 27 - 34
Do Exercise questions on pg. 98 #'s 28 - 31 and 33-34
Do Problems on pg 98 #'s 3 and 4

11/11 Chemistry update and homework due 11/18
Hi folks,
Today we took the time to review and wrap up (almost) the heat vs. temperature unit we've been working on for the past several weeks. It is a very confusing unit, probably the most difficult of the year, and so we took a bit more time to make sure everyone has some grasp of the concepts.
Here are a few websites for the concepts we've been covering the last two weeks. They do a nice job giving examples of the problems and solutions. After taking a look at these, I hope you all feel much more comfortable with these types of problems. As always, DON'T HESITATE, to contact me if you have any questions.
http://www.chemteam.info/Thermochem/Time-Temperature-Graph.html Go through the steps and try to answer the problems. Write down your answers, then feel free to look at the answers.

Hi folks,
Nathan caught a typo on the homework answers. Question 2c for 20g of water, the final temp should be 141 not 131. Good catch Nathan!

11/4 chem update and homework due 11/11
Hi folks,
Today we did a very complicated and detailed lab where we tried to determine the specific heat of lead. Next week we will talk about this a bit more and go over some of these heat problems. We will also add a couple of more things to this heat/temperature concept.
Homework for this week is to finish the lab that you started in class (the specific heat of lead is included in the .pdf).
AND complete the enclosed .pdf. I included the answers at the bottom so that you can test to see if you really understand the problems. These problems will be on an upcoming quiz so be sure to understand them as best as you can. Feel free to email me if you get stuck.
