UNIT 4 - Chemical Systems and Equilibrium

Terminology of the unit was introduced, especially steady state and dynamic equilibrium.  Refer to text p.422, 424-top of 431.  There is a good model of dynamic equilibrium at http://phet.colorado.edu/en/simulation/soluble-salts.  Click on the "Run Now" button, and shake some salt into the water.  Observe, then shake enough to form a saturated solution (there will be salt crystals forming on the bottom).  Watch the salt crystals carefully - this is dynamic equilibrium.
Homework:  Read p.424 and define bold terms; read p.429 and describe continuous and batch systems; read p.430-431 and answer p.437 #1 and p.438 #10
