An atom is the fundamental unit of matter and it contains an equal number of protons and electrons in its nucleus which makes it electrically neutral. An ion however, is an atom containing an unequal number of protons and electrons which means it will either carry a net positive charge or negative charge depending on whether there are more electrons or protons.

Answer:
The solute that is most likely soluble in hexane is S₈
Explanation:
S₈ is a non-polar solute that exhibits the same characteristics and properties as hexane. Following the common principle "like dissolves like"; polar compounds will be soluble in polar solvents while non-polar compounds will be soluble in non-polar solvents. As such, since S₈ is non-polar, then it will be soluble in hexane.
Answer:
Ethane molecules have no hydrogen bonds and need less energy to separate.
Explanation:
Ethane: has no hydrogen bonding, it has low melting, boiling points, and is a gas at room temperature.
Water: has strong hydrogen bonding between H and O, has relatively high melting and boiling points.
