Gasoline is a common fuel. most gas stations sell multiple grades of gasoline. these grades are distinguished by their octane content. octane (c8h18) is one of the components of gasoline, which may also contain many other types of hydrocarbons (such as decane, dodecane, and nonane). the fraction of gasoline that is made up of octane affects how the gasoline burns in a car’s engine. higher octane ratings are typically more expensive and can improve performance in certain types of engines. is gasoline a compound or a mixture?

The answer to your question is: Gasoline is a mixture of hydrocarbons.

Explanation:

A mixture is composed by 2 or more compounds.

A compound is a pure substance.

According to the paragraph, gasoline is composed by octane, nonane, decane, dodecane, etc, each of these compounds is different, so gasoline is a mixture of hydrocarbons.

Hydrocarbons are composed only by carbon and hydrogen. we can distinguish them by the number of carbons in their structure.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
