Question

which glass shows a homogeneous mixture and which shows a heterogeneous mixture? explain how you know.

Explanation:

A homogeneous mixture has a uniform composition throughout. Sugar dissolves in water, creating a uniform solution. A heterogeneous mixture has a non - uniform composition. Sand does not dissolve in water; it settles at the bottom, showing distinct components.

Answer:

The glass with sugar and water shows a homogeneous mixture because sugar dissolves uniformly in water. The glass with sand and water shows a heterogeneous mixture because sand does not dissolve and settles (non - uniform composition).
