HON CHEMISTRY: Great job today! Way to apply chemistry to your everyday life!!
I think you’ll find that percent composition problems are super easy to catch on to. First, though, be sure you know which “type” of percent composition you’re trying to fine.

It’s just plug and play from there! 🙂
CHEMISTRY: Did you get the homework change yesterday? Your only written homework is to do the first two Chemical Formula Practice from sciencegeek.net that are listed on the bottom of the syllabus. Be sure and check the syllabus for how you are supposed to turn it in! Also a good idea to check the syllabus for the web post comment topic!
