13th Edition

Instructions are given for the 11th, 12th, and 13th Editions.

You'll find that textbooks will mention names or formulas for substances in their questions but not say what that substance is. You'll find that I want you to look up what they are talking about. Being at the computer, it's easy to do that.

Be sure to go through my online tutorial of "Classifying: Calming the Chaos" first.
I find it interesting that the 11th edition had the same idea I had about chaos. Here is a quote from that textbook. It's the first two sentences of Chapter 3.

"Throughout our lives, we seek to bring order into the chao that surrounds us. To do this we classify things according to similarities."

Chapter 3: Elements and Compounds:
11th Edition, p44-60
12th Edition, , p47-60
13th Edition, , p43-55

Read the whole chapter. Much is covered in my online tutorial, but there are some addition information here.

Percent distribution of Elements:
11th Edition, section 3.5, pg 49-51:
12th Edition, section 3.2, pg. 49-50

Read these few pages. I make reference to them in the quiz.
