They are all homogeneous.

Are you sure? Because on my sheet it says 3 hetero and 2 homo.

At room temp, glycerol and water are liquids, if that's what you're looking for. :dontknow:

The rest are solids, though you can dissolve them to make solutions.

So you mean at room temperature, the rest are heterogeneous? Solutions or homogeneous can only be liquid and gas?

Yep, at room temp the rest are solid. That's the only big difference I can see in the physical properties of the items you've listed.

By solid do you mean heterogeneous?

So
-glyercol - homo
-copper (II) sulfate - hetero
-calcium carbonate - hetero
-sugar - hetero
-water - homo

Is that right?
