Calculate the deposition flux of no2 to cucumin dye on paper given that the indoor concentration of no2 is 10ppb and the deposition velocity of no2 to paper is 2.5x10-5 ms-1 and that 1 mg of dye is painted onto watercolour paper (5 cm x 10 cm). assuming that all no2 coming onto the paper surface will attack the dye molecules calculate the time taken to destroy all the dye on the paper.

The isotonic saline solution described in part a is connected to an unknown solution via a semipermeable membrane, the unknown solution level drops. based on this information, what can be said about these two solutions?

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.
