Heat of Formation Lab

Hey you guys! Today was basically a lab/work day. In the beginning of class we started by having Mr. Lieberman explain to us how to to the questions after the lab. If you don't remeber, or you didn't write them here it is:
Question 2. Use q=m x c x \Delta T
3. The equal opposite of #2 and convert into kilojoules
4. Do this in the same format as #2 from the pre-lab
5. Use 986.1 kJ as your theoretical amount
The lab itself was pretty easy to follow. After massing the the calcium metal, you had to place it in the calorimeter with aproximately 100 mL of water. After doing that a temperature had to be taken find the amount of heat created by the reaction. When everyone was done we did any work that we had not finished. All of this work will be turned in tomorrow. This includes 2 labs, 4 worksheets, book problems, and a webassign. For review here is a link to all of the notes we have done this chapter:
As well here is a link to all of the answers for the worksheets in case you are unsure about how to do something. http://gbs-moodle.glenbrook225.org/moodle/mod/resource/view.php?id=1054
Well this is it for today! Good luck to everyone for tomorrow. The next scribe is Stephanie K.
