Week of April 4, 2011

Welcome back from Spring Break!  I hope that everyone had a restfull break, and is ready to come back and learn some more Chemistry!  This week we'll be finishing up Unit 11 by discussing and working with calorimetry.  We'll also be starting Unit 12, Industrial Chemistry.  The test for Unit 12 will be on Friday, April 15th.

Monday:  Today we did a Science Section ACT Practice test.  I also haded out an Intro to Calorimetry problem.  You should have worked for 15-20 min on solving the intro problem.  If you can't solve it, at least work out some logical steps to try and solve it.

Tuesday:  Have your Introduction to Calorimetry ready to go when you walk in.  Remember, you should have spent 15 minutes trying to work on some logic on how to solve the problem.  We started our discussion on Calorimetry today after a group activity solving the introductory problem from Monday. We also got a calorimetry worksheet. 

The following two images show a solution for the Intro to Calorimetry Problem:

If you didn't like the two equation solution, then you could have made one master equation.  My logic for it is seen in the last image for today.

Wednesday:  We did a calorimetry activity in class today to show how specific heat capacity values are calculated.   I also handed out the RSG for Unit 12.  You should begin working on that, with a goal of having it done by Thursday, April 14th.

If you need to do makeup activity (or redo the activity) here's some sample data.  On a blank sheet of paper, neatly show all work for finding the specific heat of the unknown metal. Circle your final answer with units.


Thursday:  Today we did a lab on chemical equilibrium.  I'll post the data that I got in class here.  Note: This is class average data, not individual group data.

Friday:  Today we started notes on Unit 8.1, which introduced the ideas of reversible reactions, chemical equilibirum, and dynamic equilibrium.  We compared our lab results.   You should have your RSG done through chapter 8.2.
