When solutions containing 1.00 g ofBaCl2 and 1.00 g ofNa2SO4 were mixed, solid BaSO4 formed. The BaSO4 precipitate wasfiltered out of the solution, allowed to dry, and then weighed. Themass of BaSO4 that was isolated from solution was 1.04 g. Use thisinformation to answer the following questions. Pay close attentionto the proper use and reporting of significant figures andunits.

(a) Write a balancedchemical equation that shows the reactionthat occurs when an aqueous solution of BaCl2 reacts with anaqueous solution of Na2SO4 to form aqueous sodium chloride andsolid BaSO4. In your equation, you should indicate the physicalstates of each reactant and product.

(b) Calculate the moles of BaCl2 that areavailable for reaction.

(c) Calculate the grams ofBaSO4 that should form if allof the available BaCl2reacts.

(d) Calculate the moles ofNa2SO4 that are available for reaction.

(e) Calculate the grams ofBaSO4 that should form if allof the available Na2SO4reacts.

(f) Which reactant (BaCl2 orNa2SO4) is the limiting reagent in this reaction?Why?

(g) What is the theoreticalyield of BaSO4?

(h) What is the percent yield of BaSO4?

(i) If this reaction went tocompletion, then how many grams of the excess reagent should remain after the reaction is complete?
