On a trip to the natural history museum you find two minerals that are similar in color. you can see from their chemical formulas that one mineral contains the elements zinc, carbon, and oxygen. the other mineral contains the elements zinc, silicon, oxygen, and hydrogen. your friend tells you that the minerals are in the same mineral group. do you agree? explain your reasoning.

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

Table sugar completely dissolved in water is an example of a?

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.
