a: water ~

What:
"To explain why water and oil do not mix, we will find out that water is like a magnet, but instead of magnetic north and south poles, it has plus and minus electrical poles. The effect is the same. The plus end of water is attracted to the negative end of a different water molecule. The plus end is where the two hydrogens attach to the oxygen atom. "
