If 3.5 moles of nitrogen monoxide (no) react with 6.0 moles of oxygen gas (o2), how many moles of the product can be formed and how many moles of the excess reactant will be left over when the reaction is complete? show all of your work. unbalanced equation: no + o2 “yields”/ no2

This is a characteristic of the elements in the periodic table that shows a pattern. it may increase or decrease across or down the table.

The molality of calcium chloride (cacl2) in an aqueous solution is 2.46 m. what is mole fraction of the solute?

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.
