Chemistry 11-3-17 Practicing Chemical Formulas

CHEMISTRY: Does writing and naming chemical formulas tie you in knots? I hope today’s practice helped!

The vodcast below is the work we did in class going over last night’s homework: #21, 23, 41, and 44.

Keep working on it – both practicing and memorizing polyatomic ions!!! The knots are all going to come unraveled and you are going to master this!!

Physics 11-3-17 Friction & Forces on an Incline Problems Review

PHYSICS: Girl on a sled coasts down a hill, box is pushed up a hill… Is it starting to make a little more sense? Here’s our review of problems 40, 52, and 48 (I think).

Here’s the thing. You can watch me or someone else do a thousand problems (okay, maybe not a thousand – but a lot!), and it won’t help. I don’t want you to copy what I do, I want you copy why I’m doing it. Make sense? You’re getting it…keep sledding and watch out for net forces!

Hon Chemistry 11-3-17 Percent Composition

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. Also make sure you can write chemical formulas (I won’t give them to you!) and that you’ve memorized the formulas for acids and those chemical names and formulas for common substances. It’s just plug and play from there! 🙂
