A gas containing H2S and CO2 is bubbled through methanol at 4 degrees C. From the bottom of the tank to the top, 80% of the H2S is absorbed by the methanol. The volume fraction of H2S in the entering gas is .6. The tank is 20 ft tall, and the gas is introduced at the bottom of the tank. The volumetric flow rate of the entering gas is 15 L/min. The gas enters at room temperature, but by the time it has bubbled through the tank, the temperature can be assumed to be the same temp as the methanol.
a.) What is the volumetric flow rate of the exiting gas?
b.) What pressure is the tank under?
Suppose a bone from an ancient human contains 17.5% of the {rm C}-14 found in living organisms. How old is the bone?
Its titrated with NaOH. Being a triprotic and having 3 acid dissociation constants Ka1, Ka2, Ka3 one would expect to see three equivalence points. Why does it only show two equivalence points
Prior to their phaseout in the 1980s, chemicals containing lead were commonly added to gasoline as anti-knocking agents. A 1.805 g sample of one such additive containing only lead, carbon, and hydrogen was burned in an oxygen rich environment.
