Homework: same as Monday (see Monday!)

Monday, Jan. 12th, 2009: Equilibrium

Monday:

1. Warm-up: on board (see warm-up notebooklet)
2. Collect homework; assign new homework
3. Intro. to equilibrium: Equations can run forwards and backwards.
4. Equilibrium lab: Straw Equilibrium

Homework: 1. QP explanation to someone due Jan. 14th. QP improvements AND extension due Jan. 14th. Final draft, all typed, due Jan. 28th. GET IT IN EARLY FOR EXTRA CREDIT! 2. CST worksheet on equilibrium done (all sections except thermodynamics done).

Sunday, January 11, 2009
