<span>Recrystallization
is another method of purification of solids in which an impure solid is
crystallize repeatedly to obtain amore pure solid and a larger one. Ethanol is
better suited as solvent in recrystallization of benzene than acetone because
it becomes soluble with benzene at a higher temperature. Ethanol is non polar
and may react well with benzyl but acetone are is non polar. A difference in
their polarity, especially in heating both benzyl and the solvent can lead to
more impurities that cannot be removed.</span>
Answer:
If a solution conducts electricity, it is positive evidence that solute dissolved in solvent is electrolyte.

Explanation:
Substances can be found in nature in different <em>aggregation states. </em>
Agreggation states can be liquid, gas or solid.
The problem asks about which substance can be found in room temperature as <em>liquid.</em> Each subtances has different physical and chemical properties that determines in which state you can find them at room temperature.
Hydrogen peroxide is the only substance listed that is in liquid state at room temperature, all other substances are in gas state at room temperature.
