An aqueous potassium nitrate solution containing 60.0 wt% kno3 at 80°c is fed to a cooling crystallizer in which the temperature is reduced to 25°c. the solubility chart for kno3 in water is provided. a)is the initial solution saturated? b)at what temperature will the first crystals be formed? c)what is the percentage of kno3 in the feed that will drop out of solution?

Find the empirical formula of each of the following compounds. given mass or for each element in a sample of the compound 3,611 g ca; 6.389 g c1

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.

Which diagram represents the phase tha occurs after a solid melts?
