QUESTION 26 A student finds that 15.2 g of nitrogen will react with (A) 17.37 g (B) 34.74 g or (C) 43.43 g of oxygen to form three
different compounds.
1. Determine the mass of oxygen per gram of nitrogen for each of these three
compounds.
2. Divide your answers in 1) by the smallest value to try and obtain a whole number ratio
for the three masses (of oxygen). With what integer can you multiply these three
numbers to obtain whole numbers for them all?
3. Which Law is illustrated

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.
