Acertain satellite orbiting earth has a speed of about 17,000 miles/hour. what is its approximate speed expressed to the correct number of significant figures in kilometers/second? one kilometer is about 0.62 mile, and there are 3,600 seconds in an hour.

Identify and describe the three ways that mutations affect organisms.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

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.
