This week in Advanced Chemistry:
MONDAY
We finished up our laboratory discussion of Physical and Chemical Changes. We reviewed SOL Questions and did a lab on separation techniques. These included chromatography, filtration, distillation, and electrolysis.
TUESDAY
We discussed the separation techniques lab and students took notes on matter. Separation of mixtures can be done with a physical change. Decomposition of compounds can be done with a chemical change. Elements can't be separated by physical or chemical changes.
WEDNESDAY = We reviewed homework and students took a quiz on matter.
THURSDAY = We discussed the process of writing chemical equations and did a lab involving baking soda and vinegar.
FRIDAY = We discussed the law of conservation of mass and did a few example problems involving percent composition.
The unit 2 test is scheduled for Tuesday. The homework for this weekend is to do the Unit 2 Practice Test.
In AP Chemistry, we did a lab on Monday involving the empirical formula of hydrates. On Wednesday we reviewed a Chapter 3 practice test. On Friday we had a demo of the formation of tin oxide, and wrapped up Chapter 3. Students were given a take-home test for Chapter 3. This test is due on Monday morning when class begins
