how mixture are different from compound

Differences between mixtures and compounds

MixturesCompounds
 A mixture can be separated into its constituents by physical processes (filtration, evaporation, sublimation, distillation) A compound cannot be separated into its constituents by physical processes. It can be separated by chemical means
 A mixture shows the properties of its constituents A compound has a new set of properties different from its constituents
 Composition of a mixture varies and the constituents are present in any proportion by weight. It does not have a definite formula The composition of a compound is fixed and the constituents are present in fixed proportions by weight. It has a definite formula
 The constituents do not react chemically, thus no energy changes take place Chemical reactions take place and energy changes in the form of heat and light are involved
 A mixture does not have a fixed melting point and boiling point Examples: air, sand and salt A compound has a fixed melting point and boiling point Examples: H2O (water), FeS (iron sulphide)
