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 Friday morning, 7:15 A.M. Also, don’t forget make-up labs are Thursday morning at 7:15 A.M. and Thursday afternoon at 3:30 P.M. 🙂
HON CHEMISTRY – Hey guys, Here’s the lecture from Thursday on how scientists began to determine the structure of the atom and the existence of subatomic particles. FYI – as we go on, make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries. Wow, that’s a mouthful!
Don’t forget the videos in the Vodpod below! They will help a lot as you review the different scientists experiments. BTW – Do you think there could be anything smaller? Than an electron, I mean??
One last thing – remember that make-up labs are Thursday morning at 7:15 A.M. and Thursday afternoon at 3:30 P.M. 🙂
PHYSICS: Great job on the problems today – good connections between work and energy. I think you’ll like using the work-energy theorem, it’ll save you some time and a couple of steps. Don’t forget about friction!
