A mixture is not a compound because

• mixtures are chemically combined

• mixtures are always in fixed proportions

• mixtures are not always in fixed proportions

• mixtures can only be elements

A mixture is not the same as a substance, but it is

• more similar to a compound

• made of substances

• always going through chemical changes

• never conserved

• it is made of 2 elements chemically combined

• it is a pure substance

• it has particles such as dust and water in it

• it is more like a suspension
