Answer:

I'll create more, but this is the limit (took a while, so brainlist plwease)

ヾ(^∇^)

Explanation:

Gasoline is a mixture of liquid organic materials. You already know about one of these materials—ethanol. Most gasoline in the United States is about 10% ethanol. The other materials in gasoline are mostly hydrocarbons: organic molecules made of only hydrogen and carbon. Because ethanol has oxygen atoms it is not a hydrocarbon.

One hydrocarbon molecule in gasoline is octane: C8H18. Here is the structure of an octane molecule. All of the different hydrocarbon molecules in gasoline have about the same amount of energy. However, octane is different from some of the other organic molecules in gasoline because octane burns very smoothly.

At a gas pump, people can choose from types of gasoline

with different octane ratings. All of the different grades have the same amount of energy, but high-octane gasoline burns more smoothly. The octane ratings on a gas pump indicate how smoothly the gasoline burns: an octane rating of 100 means that the gasoline burns as smoothly as pure octane.

(High-grade gasoline is more expensive. Most cars do not need gasoline that burns so smoothly, so for most cars it makes sense to get the less expensive lower-octane gasoline that has just as much energy.)
