Exp 15 help file

[robert zellmer]

I've received questions about the exp 15 help file I have on the
class web page.  Item #12 states "When answering the report questions ..."
That part of this item was left from when there were report questions.
You should be addressing this item in the Discussion section.

12) In the Discussion section address how solubility changes with temp.

     Does the trend you see indicate whether the reaction is endothermic
     or exothermic?

     Does this mean heat is a reactant or product in the process?  See
     the equations shown on page 17 and write similar equations in the
     discussion section.  Your equations should show the appropriate
     solute and ions in solution as well as the heat (as reactant or
     product).

I've updated my help file.

Also, someone asked about the "Points to Consider" on page 23.  These
are there to help you with some of the things you should discuss in
the Results/Discussion section.
