A chemist must determine the empirical formula of an ionic compound composed only of iron and oxygen. Chemical analysis reveals that the compound is composed of 1.252 moles of iron and 1.879 moles of oxygen. What is the empirical formula of this compound?

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

How many molecules are in 6.0 moles of methane

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.
