15. Chang 3.89. 6.00 kg calcium fluoride is reacted with excess sulfuric acid. The reaction yields 2.86 kg HF. Balanced reaction: CaF2 + H2SO4 → CaSO4 + 2HF Calculate the % yield of the reaction.

16. Chang 3.86 (but changed from Chang's version). 48.2 g HCl is added to 74.7 g MnO2. The balanced reaction is: MnO2 + 4HCl → MnCl2 + Cl2 + 2 H2O a) How much (g) Cl2 can be produced? b) How much (g) of the excess reactant will be left over?
