Okay so cool, we finished our quiz on Molecular and Empirical Forumla, along with Percent Composition!
there isnt alot to say about this because we didnt have an actual lesson before or after the quiz...
I found that the quiz was quite straight forward! there was nothing on that quiz that Ms. Chen didnt
teach us. (im not being a suck up here)
Hopefully its not one of those quizzes where i thought i did well, but when i get it back... i didnt do so great.
If your still not getting it here are some VIDEOS:
