I've watched so many videos on this and was lost in chem lecture but your video helped tremendously! Thank you so much!

thanks for this vid....since my teacher is doing such a crappy job teaching, this rlly does help me

Thanks man, that helped clear that up for me!

Thank you so much for your videos, they are just great... If I were you, I would put it up in iTune U, so people can download them... Thank you once again
