A mixture is formed when substances are combined physically rather than chemically. Each substance keeps its own properties, and proportions can change.
Unlike Compounds, mixtures can often be separated using physical methods (for example, using a magnet to separate iron from sulfur in an iron-sulfur mixture).
The source contrasts iron + sulfur as a mixture (before heating) with iron sulfide as a compound (after heating and reaction).
