Re: Extensive v. Intensive Property [ENDORSED]

In class, I wrote in my notebook, in simple terms, that with extensive properties, the scale of the matter is important (volume), and with intensive properties, the amount doesn't matter (density).

Re: HW F11

Just wondering, is it important that we learn all of the polyatomic ions for the first test/subsequent tests? I know a few, but is there a list somewhere of ones we should memorize or something? Thanks!

Re: formula units [ENDORSED]

This thread is similar to a question I jsut asked. I'm just confused on when to use formula units and when to use other names, like ions, atoms, or molecules? Thanks!

Forumula Units?

I'm a little bit confused on when to use formula units, atoms, or molecules. How do you know which one to use and when? Are there certain compounds specific to each one? I came upon this question when doing question 9E in the 7th edition book.
Thank you!
