Os Qualia e as Experiências Químicas

(1) "Here ethanol (ethyl alcohol) has been mixed with water (left tube) and with carbon tetrachloride (right tube). Note that ethanol mixes with both. Half of each ethanol molecule contains a polar C-O-H group and the other half contains essentially nonpolar C-H bonds. That gives ethanol molecules both polar and nonpolar characteristics."

(2) "Acetone is another molecular material with both polar and nonpolar characteristics. Here acetone has been added to water (left tube) and carbon tetrachloride (right tube). As you can see, it has mixed with both the polar water molecules and with the nonpolar carbontetrachloride molecules."
