- Experimental observations show that thiocyanate (SCN- ), the conjugate base of thiocyanic acid (pKa = 1.1 at 25 °C), is quite soluble in neutral water at pH > 2. In the space provided below, explain this experimental observation. That is, why does SCN– readily dissolve in water when the pH > 2?What is the predominant form of cyclohexylamine at pH 9.5? Approximately what fraction is in this form?please provide the machanisms of 1a, 1e, 1f
- The crocodile, which can remain under water without breathing for up to 1 h, drowns its air-breathing prey and then dines at its leisure. 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? Explain your answer.The ionization of monoprotic organic acid with a Ka of 6.7 × 10 -4 is 3.5%.Calculate the molecular weight of this monoprotic organic acid if 100 g of it is dissolved in 1 L of water.

- 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)? If 0.257L of tetraethylstannane (d= 1.187 g/mL) were actually isolated in this experiment, what was the percent yield?1.
