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?
Why is the boiling point of octane, C8H18, higher than that of methane, CH4, if they are both nonpolar molecules? 7-Using a diagram to illustrate your answer, explain the effect of temperature on the vapor pressure of a liquid.
Calcium nitrate will react with ammonium chloride at slightly elevated temperatures, as represented in the equation Ca(NO3)2(s)+2NH4Cl(s)--->2N2o(g)+CaCl2(s)+4H2O(g)

Air coming from a painting operation contains 10.0 wt% acetone. The total flow rate of the air/acetone stream is 1.00x103 lbm/min. This stream is sent to a scrubbing system where it is mixed with water.
How To Draw a Free Electron Model Energy Level Scheme for Hexatriene, give correct energy assignment and quantum number and include correct spin
What kind of compound is 2,3-dihydroxypentane? From what precursor do you synthesize the kind of compound that 2,3-dihydroxypentane is?
HNO3 has 2 dissociating ions whereas Al(NO3)3 has 4, which should result in a higher conductance value. Would this have something to do with aluminum nitrate being paired with water as a solid?
