Here's your first actual chemistry video lesson--aren't you lucky?! There are two videos to watch in this one and a quiz to take on the right. If there is ANYTHING you don't understand, go to the bottom of this lesson where it says "QUESTIONS AND ANSWERS," and ask away. You won't be the only one with a question, so ask it for everyone's benefit. I shall answer it in that same section so we're all clear. If you have suggestions on making the video stronger, or if you have some other useful link, please put it there, too. I won't be offended if one of you has a better way to describe this. Anything that will make the material more understandable is fantastic.
