Balance the following chemical equation, then answer the following question.
c8h18(g) + o2(g) →co2(g)+h2o(g)
how many grams of oxygen are required to react with 10.0 grams of octane (c8h18) in the combustion of octane in gasoline?

how do i do this?

Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

Identify a strong intermolecular force of attraction between an alcohol

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.
