On Monday we will complete our demonstrations. Please use the break time to prepare, since class will be a little shorter (Mr. DeLeo needs a little extra time--I guess you are doing plays??)  I will send home a take-at-home test, due on Thursday.

Homework is the worksheets10-2 Molar Mass - prime numbers only, and 10-3 Mole conversion, just the odds [insert movie references here].  This worksheet includes converting moles of gas; you can probably  figure that out on your own but we will not have those kinds of problems on the test. Worksheets and Answers  (just a note: a lot of these problems have to do with the moles of a gas, which we haven't really discussed.  Enough to say, all gases take up the same amount of space at room temperature and sea level (standard temperature and pressure - STP)  and therefore 1 mole of any gas = 22.4 liters/mole) which fills about 6 balloons.

Review vocabulary, elements, periodic table, naming ionic compounds, balancing equations, types of reactions.

Also, Jacqueline, Anthony, Abel, and Brina are up for demonstration experiments on Monday.  Let me know what you might need, asap.  Simple is just fine.
