CHEMISTRY: One man’s rust is another student’s lesson in chemistry! From Wednesday – here’s the lecture on oxidation numbers. Lots of good practice at the end on this one. Need help? Don’t forget the practice at sciencegeek.net. Go to sciencegeek.net
Good luck studying for the Chemical Formulas & Memorization quiz tomorrow! You need to know: polyatomic ions, monatomic ions (but you can get these off the periodic table), acids, and the chemical names and formulas of common substances. That’s a lot!
Ms. skinner thank you for letting us work on problems in class i really need the practice!
Ms, Skinner, I’ll use the formula to calculate the oxidation number to practise more.
When is our next science in the news due?
it took me a while to memorize the chemical formulas, but i think its really helping me on the homework now!
I think I’m starting to understand this now.
I am just starting to understand all the rules and exceptins for all the classification of the elements and compounds. I will definately be attending the help session this week.
Ms. Skinner-Do you think we could work a few more of these problems soon? I think I’m starting to understand but I could use some practice!
So when is our next help session? I’m definitely plannning on attending.
You were right! this is helping, thanks (:
