Things that can be separated by physical means are mixtures. There are two types of mixtures: homogeneous and heterogeneous. In a heterogeneous mixture, you can see the different components that make up the mixture. You can't see the components in a homogeneous mixture. Things that can only be separated by chemical means are compounds.
An element - substance - NOT a mixture.
The substance that dissolves another substance is called a solvent. The substance that is dissolved is called the solute.
A pure substance is classified by having a definite and constant composition. The substance can be either an element or a compound, but what makes the substance pure, is that it does not vary.
