Chemistry 10-18-11 Binary Molecular Formulas

CHEMISTRY: Okay, I’m not saying that learning to name and write chemical formulas is as bad as a jellyfish sting, but you do have to really, really pay attention to the details!! Here’s the lecture from today on writing formulas and names for binary molecular compounds. Part of it’s really similar to what you learned to do last week for ionic compounds, but another part is totally different.

Make sure you keep everything straight. Do something that will organize all the information for you, so you won’t get confused. Also, don’t forget the lists you have to memorize, especially the one for next Tuesday – polyatomic ions!! And practice, practice, practice!!!

Hon Chemistry 10-18-11 Using Chemical Formulas – Moles & Mass

HON CHEMISTRY: Good job using chemical formulas as tools today! So it turns out there are tons of ways that you can use them. Like finding molar mass, moles, and molecules! Did it all sound familiar to you – like we were repeating yesterday’s lecture? Here’s the lecture from Tuesday.
