Question

what is gasoline an example of? a mixture of liquid in liquid a mixture of solid in liquid a pure substance a mixture of gas in liquid

Explanation:

Gasoline is a mixture of different hydrocarbons (liquids) like various alkanes, so it's a mixture of liquid in liquid. A pure substance has a fixed composition, but gasoline has varying components. A mixture of solid in liquid would involve a solid solute (like salt in water), and gasoline has no solid. A mixture of gas in liquid would have a gaseous solute (like carbon dioxide in soda), which isn't the case for gasoline.

Answer:

a mixture of liquid in liquid
