Re:       Recitation 3, week of January 22


     Attached is a key to the quizzes in both sections, in case you
have students attending from both.  Make another effort to get
people in your section going to the right lecture (or vice versa),
and give a little time for the students to firm up their groups,
and to get late registrants into a group.

Go over the following:

From Chapter 2:

     Naming ionic compounds and acids
     Naming binary molecular compounds
     Writing formulas from names

From Chapter 3:

     Writing and balancing chemical equations.
     Completing and balancing combustion equations.
     Calculating molecular and formula weights.  
     Calculating atomic weights from isotope distribution.

     This will probably take up most of your time.  Next comes the
mole concept, but I doubt if I will get to that in time to put it
on this week's quiz.
