By evaporation.
No. You should use evaporation of the water to separate the sugar and water.
Evaporate the water off and recondense it.
No. If the sugar is completely dissolved and then mixed thoroughly, it would be homogeneous.
By evaporating the water out, which precipitates the sugar back into its crystalline form.
This would be a mixture, because you could easily separate the water and sugar again by boiling the water.
It could be both, but if the sugar is completely dissolved and then mixed thoroughly, it would be homogeneous.
simply by crystallization of sugar or by fractional distillation
A magnet will cause the iron to adhere and separate. Or adding water will dissolve the sugar and the iron can be filtered out and then the water evaporated from the sugar.
You could try running water through it (which would dissolve the sugar), collecting the water, and evaporate it to get the sugar back.
it is easy to separate sugar from water. allow the water to evaporate to get back sugar. splitting of water into hydrogen and oxygen requires more energy than the above.
Mix in a little water, dissolve the sugar. Filter to separate the bird seed. Evaporate the water and the sugar crystals will reappear.
For example, evaporation can be used to separate saltwater and sugar and water.
