A student reacts 35.3 grams of sodium carbonate, Na2CO3, with 21.1 grams of calcium chloride, CaCl2. After the reaction is complete, the student finds they produced 12.8 grams of calcium carbonate, CaCO3, which precipitated out of the solution that still contains sodium chloride, NaCl. What is the student's percent yield in this reaction?

(You will need to write a overall reaction for the given reactants and products, balance the equation, find the molar masses of the chemicals used, then solve to determine the limiting reactant, then use that information to determine the percent yield of the reaction.)
