Chemistry 6/4/15

  What kind of “shifts” did you see yesterday?  In the popular restaurant model, how could you “shift” the number of people in the restaurant?  HW:  “Direction of shift” for each System completed  Begin looking at the Data Analysis and Concept Development Questions (due Friday) Drill

 Objective  IWBAT:  Apply Le Chatelier’s principle to a lab  Determine if a reaction is reactant or product favored

Prepare a data table for Systems 2, 3, and 5 in your lab notebook.

  SAFETY – goggles, aprons, closed toe shoes  If you spill, wipe down the spill and rinse off hands  SET UP –  You will be doing two Systems today, two tomorrow  DISPOSAL – all waste goes into the proper waste disposal container (in the center)  DO NOT THROW AWAY TEST TUBES  COMPLETE THE “SHIFT” COLUMN IN THE DATA TABLE.

  Return to your seat, and classify the shifts for the two Systems.  Read over the Data Analysis and Concept Development Questions.  Begin answering these questions in your Lab Notebook. Done?

  How is equilibrium like a see-saw? What are the “stresses” you added like?  How is equilibrium NOT like a see- saw? Closure
