Chemical Equations Best

Check out this SlideShare Presentation:

CHAPTER 9

GREAT slideshows up http://www.slideshare.net/mrkalember

especially the one that says BEST !! good review of NET ionic equations, spectator ions, etc.

check this HELP out

Hey chemistry students, when you're bored or need help check out the powerpoints I have put up at www.slideshare.net/mrkalember


Go here and you'll have all 14 of my powerpoints for chemical formulas and memorizing ions and such. notice i've duplicated some powerpoints by accident in uploading.

Here is another page with some GREAT LEWIS ELECTRON DOT practice.

good luck and study hard.

helpful test hints

BE SURE YOU CAN GIVE THE ELECTRON CONFIG, CONDENSED ELECTRON CONFIG AND PICTORIAL CONFIGs, for the EXCEPTIONS - Cu and Cr. And, why are they exceptions? (hint, half full is more stable.)

WEB help

So Monday we're starting our chapter on ATOMIC THEORY. This website (http://www.chalkbored.com/lessons/chemistry-11.htm) has some helpful information. Click on the link then scroll down to the second lesson - there is a nice powerpoint about the history of atomic theory just like we'll discuss in class.

Also here, nice review http://www.chemtutor.com/struct.htm
