A mixture of two high-boiling organic acids is to be separated from nonvolatile impurities by steam distillation at 373 K under a total pressure of 20 kPa. The organic acid mixture contains
30 mol% low boiling acid and 70 mol% high boiling acid and at 373 K the vapour pressures of
the two acids are 2.7 kPa and 1.1 kPa, respectively. The acid mixture obeys Raoult's law and
are immiscible with water. Determine the kilograms of steam required per kmol of acid
recovered

What is important to study for nios grade 12 chemistry? i have only one month left.

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.

All of the following are homogeneous mixtures except a) sugar dissolved in water. b) orange juice. c) coffee with cream. d) household vinegar. e) apple juice
