If the equation, c2h5oh (l) + 3o2 (g) → 2co2 (g) + 3h2 (l), were performed in a laboratory at room temperature, both of the gas volumes:
would depend on the surrounding temperature and pressure conditions
must always be equal because the molar ratios are the same
must always be equal because the number of representative particles is the same in the equation
could be calculated without regard to the temperature and pressure surrounding them
