Hon Chemistry 11-3-21 Binary Molecular Formulas

HON CHEMISTRY: Okay, I’m not saying that learning to name and write chemical formulas is as bad as a jellyfish sting (you’ll get that in a minute!), but you do have to really, really pay attention to the details!! Here’s our discussion on writing formulas and names for binary molecular compounds. Part of it’s really similar to what you learned to do for ionic compounds, don’t you think? The other part is totally different, though!

Make sure you keep everything straight. Find a way to organize all the information for yourself so you won’t get confused. Also, don’t forget the lists you have to memorize – chemical names for common substances, polyatomic ions, acids, and numerical prefixes. And practice, practice, practice!!!

Physics 11-3-21 Friction on Inclines

PHYSICS: Who knew snow skiing could be so complicated! Well…friction problems on an incline anyway. First, here are problems 37, 38 and 49 from the homework and then our discussion of friction problems on an incline.

Back to the problems – remember, drawing the diagram is super, super important. Label all the forces and apply the concepts you know about net forces and resultant forces – let it tell you a story. 🙂

Here is some info you might find helpful in the future:
