Equal chemical equations! H2 + Cl2 > HCl
P4 + O2 > P4O10
Na + Cl2 > NaCl
CH4 + O2 > CO2 + H2O​

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

What happened to the amount of carbon dioxide in the atmosphere from 2010–2017?

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.
