1.   The following equation represents the formation of carborundum
     by heating silica (silicon dioxide) with carbon.

     SiO2(s)   +    3C(s)  --->    SiC(s)   +   2CO(s)  

(3)(a)When 3.40 g of SiO2 is allowed to react with 3.40 g of C,
     which reagent is limiting? (Show how you calculate it)








(2)(b)How many g of SiC will be formed in the reaction?








(2)(c)How much of the excess reagent will be left over after the
     reaction?







(3)2.A compound contains 7.8% C and 92.2% Cl.  What is its
     empirical formula?  (Show your work)
