The diagram shows an electric motor. What happens within the motor when an electric current flows through the
loop of wire?

A. The loop becomes an electromagnet, which causes the loop to flip
and produce mechanical energy

B. An electric field produces mechanical energy, which causes the
loop to produce electrical energy.

C. A magnetic field causes the loop to flip, which causes the wire to
store chemical energy in the battery

D. The magnets conduct an electric current, which causes the loop to
produce and conduct electricity

Check the correct box to describe the periodic trends in electronegativity. electronegativity across a period: decreases. increases. electronegativity down a group: decreases. increases.

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.
