Question 18 1 Point How many orbitals are allowed in a sub shell ifl=1 A) 7 B 1 3 5 Question 27 1 Point m Ferrocene, [Fe(C10H10)(s);molar mass 186.03 g/mol]can be prepared by reacting 6.0 g of FeC1z(s) [molar mass=126.75 g/mol) with 4.8 g of cyclopentadiene [CsHe(); molar mass 66.01 g/mol)and 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 CH is limiting: 6.76 g of ferrocene could be theoretically formed; obtained 39.9 % yield FeCl, is limiting: 4.2 g of ferrocene could be theoretically formed; obtained 54.6 % yield FeCl, is limiting: 4.2 g of ferrocene could be theoretically formed; obtained 89.4 % yield C# is limiting: 0.0151 g of ferrocene could be theoretically formed; obtained 74.8 % yield
