          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.

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

(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+

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.
