Question

Why would sand and water be an example of a heterogeneous mixture? Select all that apply. Chemical bonds are formed between the sand and water. *The mixture does not have a uniform appearance. *The mixture does not maintain a uniform composition. The sand stays suspended in the water.

Answer 1

The mixture does not maintain uniform composition and sand stays suspended in water. And no, there no chemical bond between sand and water.

Answer 2

The mixture does not have a uniform appearance.
The sand stays suspended in the water. (The sand sinks actually but I think by saying suspended, they mean it does not dissolve in water)
