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. And don’t forget, help session Friday morning at 7:15ish A.M.
UPDATE: We are not doing the lab until Friday! My bad!! The lab write-up is Thursday night’s HW and is due on Friday. Sorry about that!!
Good luck studying for the polyatomic ion quiz on Friday, but is that good enough? What about the test Tuesday? For that 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!!
Thank you so much Ms.Skinner for posting this on the website. I am feeling much better now.
Lots of rules for oxidation numbers
The extra formulas on sciencegeek.com are really helping me study!
This lesson was a lot easier than I thought it would be.
Thanks for scheduling a help session on Friday! I new all the help I can get.
Will we be able to look at the periodic table during the test or do we need to memorize what elements are in the groups?
Mackenzie – You’ll always be able to look at the periodic table! 🙂
I listened to the lecture again and it really helped me. Now I understand Oxidation numbers much more.
Thanks for putting this on here it is helping me review for the test.
