 Ok.  Chapter 5 is all about stoichiometry.  The main idea of this whole chapter is the whole "dimmensional annalysis" thing.  This is also called the factor labeling method. That means all of the preportions lined up to find a solution.  The formula is. . . ?want=got/want.  That formula translates into english as "Use what information is on the periodic table, or written in the problem to find your answer."  In other words "set up preportions you know are equal until you have the factor label you are looking for."  If you have no clue what I'm talking about check out page 13.  Also review molar relationships in Chapter 4.  All of the practice problems are already worked for you in the book, so there's no reason for me to do any.  One more thing.  Since equasions don't always work the way we expect them to, there's something called an actual yeild.  When you actually put your equasion in action, there's no garuntee that exactly 5 moles of product will result.  the difference between actual and theoretical yeild is percent yeild.  Actually, what I will do, is I'll make some games to review with, how about that?
