Which best describes a heterogeneous mixture? O A. table salt and water B. alcohol and water C. oil and vinegar O D. hot tea and sugar​

C. oil and vinegar

Explanation:

A heterogeneous mixture is a mixture where the components are not uniform in composition, like oil and water. They don't mix. When you mix oil and vinegar, you have 2 layers because oil is less dense than vinegar.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

put the answers   and i could answer.
