Hon Chemistry 11-14-12 Intro to Radioactivity

HON CHEMISTRY: Great job on your presentations today. I loved to see your creativity. Good exercise for that right side of your brain!!

Welcome to nuclear chemistry! No, really, I think you’ll be surprised how much nuclear chemistry is already a part of your everyday life. And now you know where E=mc2 came from!! Here’s the lecture from Wednesday; we’ll finish the properties and begin talking about nuclear equations tomorrow.

By the way, you need to read about the life of Marie Cure. Fascinating woman of science with an incredible story!

Chemistry 11-14-12 Molecular Formulas

CHEMISTRY: Hey guys! Awesome job with empirical formulas, and now you’ve conquered writing molecular formulas! It’s just like writing empirical formulas, but with a twist at the end! By the way, if you’d like some practice or if you have questions – help session TOMORROW morning, 7:15 A.M.

Lab tomorrow on calculating the formula of a hydrate. Make sure you print and read the lab sheet. You’ll be writing this one up in your lab book. How’s the virtual lab coming? Don’t forget that the vLAB sheets are due on Friday.

BTW – speaking of labs, make-up labs are next Monday afternoon at 3:30 P.M. and Tuesday morning at 7:15 A.M. And don’t we have a test round about that time?
