Question 13 1 Point Ferrocene, [Fe(C10H10)(5),molar mass 186.03 g/mol]can be prepared by reacting 3.0 g of FeCl2(5) [molar mass=126.75 g/mol) with 5.7 g of cyclopentadiene [CH6(0);molar mass 66.01 g/moljand an excess of KOH, as shown in the following reaction FeCl2 + 2C5H5 + 2KOH FeC10H10 + 2H20 A student who carried out this reaction obtained 2.7 g of ferrocene. Of the following choices which has three correct answers? A FeCl, is limiting: 4.40 g of ferrocene could be theoretically formed; obtained 61.36 % yield Cis limiting: 0.0151 g of ferrocene could be theoretically formed; obtained 74.8 % yield 6 FeCl, is limiting: 4.2 g of ferrocene could be theoretically formed; obtained 54.6 % yield C. is limiting: 2.82 g of ferrocene could be theoretically formed; obtained 95.7% yield Question 14 1 Point The density of solution prepared by dissolving 50 g of sucrose (molar mass= 342 g/mol) in 900 g of water is 1.96 g/mL. The molarity of the solution is A) 0.552 M B) 0.614 M 0.768 M D) 0.358 M Question 15 1 Point Name the compound CuCN Copper (I) nitrate Copper (1) nitride Copper cyanide D) Copper (1) cyanide
