Elements, Compounds and Mixtures

What is a Mixture?

A mixture contains two or more substances
that have not reacted chemically with each other.
A mixture is made of little bits of each substance mixed together.

A mixture can be separated by physical methods,
a compound can not.

For example
A mixture of iron filings and sulfur can be separated
by using a magnet to attract the iron.
Iron is a magnetic material but sulfur is not.

If a mixture of iron filings and sulfur is heated
the iron reacts with the sulfur and
the compound iron sulfide is formed.
The compound iron sulfide is not a magnetic material
and cannot be separated by using a magnet.
