Question 20 1 Point Ferrocene, [Fe(C10H10)(s);molar mass 186.03 g/mol]can be prepared by reacting 3.0 g of FeCl (s) [molar mass =126.75 g/mol] with 5.7 g of cyclopentadiene [CH6;molar mass 66.01 g/molland an excess of KOH, as shown in the following reaction FeCl2 + 2C5H6 + 2KOH - FeC10H10 + 2H2O - A student who carried out this reaction obtained 2.7 g of ferrocene. Of the following choices which has three correct answers? A Feci, is limiting: 4.2 g of ferrocene could be theoretically formed; obtained 54.6 % yield B C,H, is limiting: 0.0151 g of ferrocene could be theoretically formed; obtained 74.8 % yield CH is limiting: 2.82 g of ferrocene could be theoretically formed obtained 95.7% yield V O FeCl, is limiting: 4.40 g of ferrocene could be theoretically formed; obtained 61.36 % yield 1 Point Question 21 119 minutes remaining 8 Question 21 Consider the following unbalanced redox equation PbO2 + CH Pb(OH)3 + CIO After balancing the equation in basic solution, the coefficient of OH is 2 B 2. 1 7 Question 22 119 minutes remaining 1
