Unless otherwise instructed, you may use the periodic table in the Chemistry: Problems and Solutions book for this question. Which explanation accounts for why carbon monoxide is not a polar molecule?

The electronegativity differences between carbon and oxygen are not very large.

Carbon and oxygen do not form ions.

Carbon is a metal, and oxygen is a nonmetal.

There are no hydrogen atoms in the molecule.

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.
