There is 4.60 g of methane (CH4) and it reacts with an excess amount of O2 gas during a combustion reaction
forming CO2 and H20. One of the products, carbon dioxide, fills a 5.0 L container and has a temperature of 328K.
Assuming only the carbon dioxide goes into the container and the container is closed, what is the pressure inside
the container in kPa? (Hint: need to balance an equation for the reaction and use stoichiometry)

Which is true of a liquid? it has a definite volume but not a definite mass. it has a definite mass but not a definite volume. it has a definite volume but not a definite shape. it has a definite shape but not a definite volume.

The chemical equation below shows the reaction of sodium (na) and chlorine (cl) to form sodium chloride (nacl). 2na + cl2 → 2nacl in this equation, which of the following is a reactant? i. sodium ii. chlorine iii. sodium chloride

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.
