     This quiz is take-home and open book.  You may collaborate
with others, but you would also be wise first to try taking it as
a timed exercise to practice for hour tests.  You should be able to
complete a quiz of this length in about 25 minutes.  The completed
quiz is due at the beginning of class on Friday, May 17.  

Points

1.   For the potential reactants below:
     1)   provide correct formulas in molecular form for the
          potential reactants;
     2)   provide correct formulas for the potential metathesis
          products in the molecular form;
     3)   write a balanced, net ionic equation (if there is no net
          ionic equation, say so);
     4)   state your conclusion as to whether the reaction
               a) goes forward.
               b) goes in the reverse direction.
               c) yields no net reaction.
               d) is indeterminate in direction.

(2)A.  silver acetate  +   chloric acid






(2)B.calcium carbonate  +  ammonium bromide






(4)2.Classify each of the following in three categories:
          a.  acid, base, or salt
          b.  soluble or insoluble
          c.  strong or weak electrolyte

     HI

     NH4OH

     Ca(OH)2

     AgNO3


(2)3.For each of the following displacement reactions, write no
     reaction if the reaction does not occur, or complete and
     balance the equation if the reaction does occur:

     Al   +    Zn2+


     Sn   +    Fe2=


4.   Balance the following redox reactions occurring in acid
     solution.  Show your work by:
          1.   Writing and balancing the half-reactions.
          2.   Adding the half-reactions correctly.
          3.   Reducing the balanced equation by canceling species
               appearing on both sides of the equation and
               reducing the coefficients to the lowest whole
               numbers.

     
(4)A.Cr2O72-   +    H2S   ---->    Cr3+     +     So
