How many moles of CO2 would be produced from 1 mole of oxygen (O2)? What mass of CO2 would be produced from 16 grams of oxygen (O2)? If you had 16g of O2 and 16 g of CH4, how much water would be produced (in grams)? If the reaction above produced 8g of CO2 what would be the percent yield?

Ineed to find the answer of this question because i dont understand it

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.
