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! 🙂
HON CHEMISTRY: Oooohhhh! So that’s where the pretty light comes from! Great job on these reactions! Now go forth and practice what you learned! (The balancing equations part, not the playing with magnesium part!) 🙂

PHYSICS: Collisions – they’re all around us and they all obey the law of conservation of momentum. Here’s more specific information about the proper way to differentiate and name them.
Great job with the conceptual review and setting up the problems! As you practice tonight, be sure and check for connections between the conservation of momentum and the conservation of energy. 🙂
