11. a) Using the set of titration data shown, determine the ratio of moles of KCN to toles of KMnO4 for each trial. SHOW ALL WORK (10 points) Reactant 0,0614 M KCN 0.0501 M KMnO4 Volume used -- Trial 1 15.00 ml 13.82 mL Volume used - Trial 2 10.00 ml 9.33 ml b) Based on the average for the two trials, determine the smallest whole number ratio of moles of KCN to moles of KMnO4 and write the correct balanced reactant side of the chemical equation (6 points). 12. When an aqueous solution of 7.29 g of BaCl2 was added to an aqueous solution of 6.39 g of K2SO4, a white precipitate formed. After filtering and drying the precipitate, 5.50g of BaSO4 powder was obtained. BaCl2 (aq) + K2SO4 (aq) BaSO4(s) + 2 KCl (aq) a) What is the theoretical yield of BaSO4? Show all work. (10 points) b) What is the percent yield of BaSO4? Show all work. (5 points)
