after crude oil is pumped out of the ground, it must be processed in a cracking tower. the tower separates it into less dense chemicals like butane and gasoline, and more dense chemicals like diesel fuel and tar. based on this information, crude oil can best be classified as a - a mixture of pure substances. b pure substance. c solution of heterogeneous substances. d mixture of compounds.

Answer

Brief Explanations:

Crude oil can be separated into different substances like butane, gasoline, diesel fuel and tar by physical means (in a cracking - tower). A pure substance cannot be separated into different substances by physical means. A mixture is composed of two or more substances. Compounds are pure substances made of two or more different elements chemically combined. Since crude oil is separated into different substances by physical means, it is a mixture. These substances are compounds themselves, so crude oil is a mixture of compounds.

Answer:

D. mixture of compounds
