An adaptation that aids the crocodile in doing so it that it can utilize virtually 100% of the O2in its blood whereas humans, for example, can extract only ~65% of the O2in their blood. Crocodile Hb does not bind BPG. However, crocodile deoxyHb preferentially binds HCO3ꟷ. How does this help crocodile obtain its dinner?

- Organotin compounds play a significant role in diverse industrial applications. They have been used as plastic stabilizers and as pesticides or fungicides. One method used to prepare simple tetraalkylstannanes is the controlled direct reaction of liquid tin(IV) chloride with highly reactive trialkylaluminum compounds, such as liquid triethylaluminum (Al(CzHs)3). 3SnCl4 + 4Al(C2H5)3 → 3Sn(C2H5)4 + 4AlCl3 In one experiment, 0.160 L of SnCl4 (d= 2.226 g/mL) was treated with 0.346 L of triethylaluminum (Al(C2H5)3); d = 0.835 g/mL). What is the theoretical yield in this experiment (mass of tetraethylstannane, Sn(C2H5)4)?
