Chemical Composition Test

Yesterday we had a test over chemical composition. It was mainly a math based test. The different kinds of problems that were covered included converting from mass to atoms, atoms to moles, and finding the amount of water in a compound. It wasn't a very hard test even though I might just be doing the problems completely wrong and I just don't know. At least I think I know how to do it. This might have been a quiz and we still have more of this unit to learn.

Since I'm on the subject of compounds, I thought I'd add a cool link about some toxic compounds here. I'm sure we won't be using any of these chemicals in lab, but make sure to steer clear of them. I won't be very seeing if Bactrachotoxin is actually deadly (which it is)!!!

I thought the part of this unit that talked about hydrated particles very interesting.
