chemistry - 26.02.09

For todays Chemistry lesson, i did managed to learn a few new things and also recap on some of the things that I'm familiar with. Some of the questions that went through on my mind upon seeing the sub-topics are:
What is binary covalent compound?
How do we identify it?
How do we convert formulas to names or vice versa?
Knowing my strength in Chemistry, I think this website is really useful for my learning.
