Physics 11-10-22 A Look Back at Chapter 4 Concepts

PHYSICS: Leaves gracefully falling – can you apply concepts from this chapter to explain? Practice, practice practice the problems, but don’t forget the conceptual stuff! How do parachutes work? What causes whiplash and how do seat belts work? If you get a chance, watch the Julius Sumner Miller videos on Newton’s 2nd law and 3rd law on You Tube.

Hon Chemistry 11-10-22 Using Chemical Formulas

HON CHEMISTRY: So the little mole turns out to be a pretty big deal – and a very handy tool!!

Great job today! Here’s discussion on formula mass and molar mass, and then using molar mass and Avogadro’s number as a conversion factor. You’ve got a couple of great tools – so now think through the problems and go forth and conquer!! Be sure and practice them so you don’t forget!

Chemistry 11-10-22 Chemical Formulas with Polyatomic Ions

CHEMISTRY: How about cranking it up a notch?! First we did binary ionic compounds, and now, let’s tackle formulas with polyatomic ions. Something absolutely necessary – you have got to memorize polyatomic ions – or better yet, learn them! And practice, practice, practice!!

Another great idea, click here for a copy of the Hints for Naming Chemical Formulas Flow Chart, or find it under the Worksheet/Handouts Tab. Follow it every time you name chemical formulas!!
