Aniline is produced by the hydrogenation of nitrobenzene. A small amount of cyclohexylamine is produced as a by-product. The reactions are: C6H5NO2 + 3 H2 ? C6H5NH2 + 2 H2O C6H5NO2 + 6 H2 ? C6H11NH2 + 2 H2O Nitrobenzene is fed to the reactor as a vapour, with three times the stoichiometic quantity of hydrogen. The conversion of the nitrobenzene, to all products, is 96%, and the yield to aniline 95%. The unreacted hydrogen is separated from the rector products and recycled into the reactor. The fresh hydrogen feed is 99.5% pure, the remainder being inerts. A purge is taken from the recycle stream to maintain the inerts in the recycle stream below 5%. All percentages are molar. For a feed rate of 100 kmol h-1 of nitrobenzene, calculate: (a) the fresh hydrogen….

Height of a packed-tower absorber a packed tower of the type described in Example 23.5-2 is to be used for removing 90% of the cyclohexane from a cyclohexane-air mixture by absorption into a non-volatile light oil. The gas stream enters the bottom of the tower at a volumetric rate of 363ft3/min at 30°C and at 1.05atm pressure it contains 1% cyclohexane by volume. The oil enters the top of the tower at a rate of 20 lb-mol/hr, also at 30°C, and it contains 0.3% cyclohexane on a molar basis. The vapor pressure of cyclohexane at 30°C is 121 mm Hg, and solutions of it in the oil may be considered to follow Raoult’s law.

Could you please help answer this question.
1. (2 pts) When using the standard ruler assumption, why is it important that all of the galaxies are of the same or very similar type?
2. (3 pts) There are two probable reasons why they are not the same angular size. Either they are at the same distance and have different actual sizes, or they are the same actual size but are at different distances. Can you determine which of those two reasons is the right one? Which one of these two reasons are we assuming is true under the standard ruler method?
3. (1 pt) Compare the distances to these two galaxies as determined by the standard ruler method: NGC 3147 is 22 Mpc from us, while NGC 3368….
