Homework Help: Honors Chemistry

Posted by Emily on Monday, October 19, 2009 at 11:40pm.

Can someone please explain to me how to use the stock naming system when naming chemical/ionic compounds? I reeeeaaaally do not get it. Here's some examples:

1. CaCO3
==> I know the answer is calcium carbonate, but how is it that answer?

2. FeSO4
==> The answer is ferrous sulfate, I believe, but I don't understand this either.

I've also been having trouble with the suffixes and prefixes -- my teacher does NOT explain things very well, in lectures and in notes. How do you know when to use which prefix? He said something about "if there is one less oxygen than '-ate', then it gets the ending '-ite'", and stuff like that. Can someone please explain this stuff to me? I'm sorry it's a lot, I just really want to understand this.
