CHEMISTRY: One man’s rust is another student’s lesson in chemistry! From Wednesday – here’s the lecture on oxidation numbers. Now go out and apply them! Need help? Don’t forget the practice at sciencegeek.net. Go to sciencegeek.net. Also – help session tomorrow morning at 7:15ish A.M.
UPDATE: Homework change – do the book work, make corrections to Chemical Formulas worksheet 1, and bring Worksheet 2 to class but don’t do it yet.
How have you been doing on the polyatomic ion quizzes? What about the pre-test MONDAY? For the pre-test you need to have memorized (and be able to use!!): polyatomic ions, monatomic ions (but you can get these off the periodic table), acids, prefixes, the chemical names and formulas of common substances, and the oxidation rules.
That’s a lot, but you can do it! And make double dog sure you are working hard at memorizing it all now!!
