CHEMISTRY: One man’s rust is another student’s lesson in chemistry! Here’s the lecture from today on oxidation numbers. Now it’s time to go and practice applying them! Need help? Help session tomorrow morning at 7:20ish A.M.
How did you do on the polyatomic ion quiz? And what about the pre-test on all the memorization FRIDAY? 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 how to apply the oxidation rules to write and name chemical formulas.
That’s a lot, but you can do it! And make double dog sure you are working hard at memorizing it all now!!
Chemistry 10-26-15 Oxidation Numbers from Tammy Skinner on Vimeo.
This week in chemistry we are learning oxidation numbers and I find it very interesting because I didn’t memorize my ions very well so this will be a struggle but I feel as if I memorize these better it will help all of it.
I rate myself a 6 out of 10 this week because i was confused at first on the homework we did but then after you explained it in class i now understand how to write formulas and use the stock system.
This has been a challenging week in chemistry. These chemical names and formulas are somewhat tricky. There has been much to learn and memorize. I need to practice more so I can do well on the pre test.
