Consider the following reaction:

   2NaCN + H2SO4 => Na2SO4 + 2HCN

 Given 47.44g of NaCN , and 38.72g of H2SO4
First determine which of the reactants is limiting.
What is the theoretical yield of Na2SO4 ? (you must know which is the limiting reactant to get this right!)
Answer to the hundreth's place (0.01)
Yield: *

How much of the excess reactant is CONSUMED in the reaction?
Answer to the nearest hundredth's place (0.01)
Excess Used: *
