im not sure how to answer this and i have no idea what its asking...plz help!

Because Oxygen is more abundant than octane.
in order to burn you need oxygen and oxygen is found in air almost 21%. Approaching octane which is a small sample in comparison to air makes octane the limiting reactant

in a reaction, different substances come together and make a product or products.
It is unusual in nature that the precise amounts of all of the reactants is exactly what is need to make the reaction go to completion. It is far more common that one or more of the reactants is present in excess amounts, so the amount of product that can be produced is limited by the reactant that is present in the least amount for the needs of the reaction.
This substance is the limiting reactant. when the reaction is performed to completion, there will be no more of the limiting reactant left, but the other reactants will still be present, will not have been used up completely.
whether octane or some other substance will be the limiting reactant depends on the circumstances. In open air, you will certainly have wayyyyy more oxygen than octane. However, in a closed jar half filled with liquid octane, the reverse would be true.

If you are burning the octane in open air, the octane can acquire all of the oxygen necessary for its combustion from the atmosphere. The amount of oxygen is quite vast.
