Hon Chemistry 11-1-22 Binary Molecular Formulas

HON CHEMISTRY: No audio on today’s vodcast, so here’s the same lesson from last year. Start it at about 11:24. One thing that’s not on this list is the info on binary and oxyacids that you’ll need to memorize and know for this year. You can find the list of these acids here on the class website under the worksheet tab.

So 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 11-1-22 Friction Forces on an Angle Pt 2

PHYSICS: Here’s a look at some of the friction at an angle problems – the ones where you don’t know enough. Also pushing a block on the ceiling – and a life lesson about painting ceilings. No audio today(!) so I’m posting a vodcast from a couple years ago.
