Magnesium and nitrogen react in a combination reaction to produce magnesium nitride: 3 mg + n2→ mg3n2 in a particular experiment, a 10.1-g sample of n2 reacts completely. the mass of mg consumed is g.

Consider the four elements above. which one of these elements will combine with oxygen in a 1: 1 ratio?

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.
