They are homogeneous. But they are not a mixture, so they are a pure substance
iodine crystals are homogeneous(not a mixture) more precisely a pure substance.
Iodine is an element, so a pure substance, not a mixture, (so even not homogeneous).
The iodine solution is a homogeneous mixture.
Iodine crystals can be part of a mixture, but it has to be with another element. The crystal itself can by "aqueous", or dissolved in water, but 'I' as an element is just a pure substance.
heterogeneous?
Iodine is an element.
The solution is homogeneous.
Homogeneous
The solution is homogeneous.
Iodine water is a homogeneous mixture because Iodine gets completely dissolved in water. A heterogeneous mixture is a mixture in which all componets of the mixture aren't the same phase.
homogeneous
Sugar (sucrose) dissolves completely in water, making a homogeneous solution.
Heterogeneous, generally speaking water could only be considered homogeneous if there weren't any contaminaton and is distilled without any form of pollution. Good way to remember heterogeneous vs. homogeneous. if you can separate it-it's heterogeneous. ex. on a pepperoni pizza you can pick off the cheese, the bread, and the pepperoni. this is a heterogeneous mixture.
A heterogeneous mixture is a mixture of two or more substances that are not uniformly distributed. The iodine and water in the question are not homogeneous because they are not uniformly distributed.
The solution is homogeneous.

Iodine is much more soluble in ethanol than in water, so it will usually form a homogeneous mixture. Of course, if you add more solid iodine than will dissolve in your quantity of ethanol at the temperature at which you are working, the excess solid will sink to the bottom. In that case, you have a heterogeneous mixture.

This is a homogeneous solution.
Water without insoluble impurities is homogeneous.
