A compressed liquid containing an equimolar mixture of normal pentane and normal hexane is flashed at 20oC. In this steady-state flow system 33% of the feed stream is vaporized. Explain what the system pressure is as well as what are the compositions of the liquid and vapor streams?
The Born-Haber cycle is a series of steps that represent the formation of an ionic compound from a metal and a nonmetal. For example, the steps in a Born-Haber cycle for the formation of NaCl(s) consist of sublimation of the metal Na atom
25 mL of 0.10 M HCl is mixed with 25 mL of .43 M NH3. What is the resulting pH?
Determine the final pressure, volume, temperature, and number of moles of gas when the volume is reduced by half at the time when gas is compressed? Use C p /C v = 1.3
Lead nitrate, Pb(NO3)2, reacts with sodium sulfate, Na2SO4, to make lead sulfate, PbSO4, and sodium nitrate, NaNO3. How much lead sulfate can one make from 65.05 g lead nitrate and 55.02 g sodium sulfate? Explain fully how you came to you answer. I..
A typical aspirin tablet contains 324 mg of aspirin (C9O4H8), a monoprotic acid with a Ka= 2.8x10^-4. A monoprotic acid donates a single proton. If you dissolve two aspirin tablets in a 300 mL glass of water, what is the pH of the solution
