Question

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

Answer 1

Yes it could be calculated everything that has numbers like those you calculate them and see what u get
