week 9-10, chembalancer

This was fun, I like the interactive sites. I did some from the "learning" section and some from the "review" section, and then I did the first few of the brain boggler questions and got them right! Yay! And I liked the little bits of information about the elements and molecules in the equations, for example it was nice to learn that acid rain has decreased due to better industrial pollution controls. I couldn't get the element quiz to work though -- no questions came up.
