A pure substance is a substance that has only that substance in it. One kind of molecule or atom. A homogenous mixture can have different molecules and/or atoms in it, but they have to be in the same physical state. Water mixed with honey would be a homogenous mixture, because they are both liquids. Water mixed with sand would be heterogeneous.
