Identify the correct net ionic equation for the reaction that occurs when solutions of HI and Be(OH)2 are
mixed?
2H'(aq) + Be(OH);(s) -2H,0() + Be*"(aq)
H'(aq) + OH (aq) -- H,0(1)
H (aq) + 20H (aq) - H;0(1)
D 2HI(aq) + Be(OH);(s) 2H,0(1) + Bala(s)

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 [CH();molar mass 66.01 g/moljand an
excess of KOH, as shown in the following reaction
FeCl, + 2C,H, + 2KOH FEC10H10 + 2H,0
A student who carried out this reaction obtained 2.7 g of ferrocene. Of the following choices which has
three correct answers?
FeCl, is limiting: 4.40 g of ferrocene could be theoretically formed; obtained 61.36 % yield
FeCl, is limiting 4.2 g of ferrocene could be theoretically formed; obtained 54.6 % yield
© CH, 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
