Explanation:

An element is a pure substance made of only one type of atom. A pure compound consists of two or more elements chemically combined in a fixed ratio. A pure substance is either an element or a compound. Crude oil contains different hydrocarbons (paraffins, naphthenes, aromatics, asphalytics) in various percentages, which means it is made up of multiple substances not chemically combined in a fixed - ratio. So it is a mixture.

a mixture
