Answer: water and oil (first option) and water and benzene (third option) are immiscible combinations of liquids
Explanation:
The question requires us to choose, among the options given, which of them represent immiscible mixtures, considering that water is polar, oil is non-polar and benzene is non-polar.
To solve this problem, we'll need to keep in mind that polar liquids will mix together (are miscible), although polar and non-polar liquids will not mix together (are imiscible).
Therefore, regarding water, oil and benzene, we can say:
- water is immiscible with oil and immiscible with benzene;
- oil and benzene are miscible liquids.
Considering the points made above, the best options to answer this question are the first (water and oil) and third ones (benzene and water).
