Question

Which is an example of a heterogeneous mixture?

Answer 1

The answer is d. flour and water because a mixture of flour and water is not going to be even throughout, it will be lumpy and not completely mixed.

Answer 2

A heterogeneous mixture is a mixture that is not uniform in composition which means the mixture can be separated from one another. The only answer choice that you have put up there that is of two things being mixed together and that's flour and water. I'm sorry but I don't think that any of these are an example of a heterogeneous mixture.
