Which one of the following is not a homogeneous mixture?
question 18 options:
vegetable soup
carbonated beverages
saline solution
brewed tea

The first one, vegetable soup, the reason being is that all of the other solutions, are uniform, in the sense that you can't tell apart or differentiate the components within the mixture by simply looking at, whether as in vegetable soup, assuming it has small pieces of vegetables, it is heterogenous as not all components are dissolved or present as one, there is more than 1 phase or substance that can be told apart.
