Agas cylinder is filled with 4.00 moles of oxygen gas at 300.0 k. the piston is compressed to yield a pressure of 400.0 kpa. what is the volume inside the cylinder? a 3.19 dm3 b 6.25 dm3 c 24.9 dm3 d 31.5 dm3 c

The diagram below shows the different phase transitions that occur in matter. which arrow represents the transition in which dew is formed?

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.

Which symbol can be used to indicate the pressure at which a chemical reaction is carried out? 25°c 2 atm pa
