Which food is not a heterogeneous mixture?

a. chocolate chip cookies

b. oil and vinegar dressing

c. cooking oil

d. trail mix

Option C cooking oil is not heterogenous mixture

Explanation:

Mixture is a combination more than two substances and are not chemically combined.

It is of two types Homogenous mixture and heterogenous mixture

Homo means "same".

Hetero means" different"

Homogenous mixture is a mixture which looks uniform throughout

Examples Cheese, salt solution, air, 18 carat gold

Heterogenous mixture is a mixture which looks non uniform throughout

. Examples Pizza, trail mix, salad, A mixture of oil and water

Well it's definitely not trail mix or chocolate chips so it would be so it's oil and vinegar dressing

Hope you do great

Good luck
