Question

List five characteristics by which compuond can be distinguished from mixture

Answer 1

Answer:

Compounds:

It is a pure substance

It cannot be seperated by physical method

Elements loose their properties in compounds

Its composition is fixed

It has fixed melting point

MIXTURES:

It is a impure substance

Cant be seperated by physical method

Substances forming mixture retain their properties

It has no fixed composition

It has no sharp melting point

Answer 2

Explanation:

CHARACTERISTIC 1 :

Compounds are bonded to each other chemically and not physically

Mixtures on the other hand are bonded physically

CHARACTERISTIC 2:

Compounds are pure, i.e. they consist of one type of molecules, eg, Sugar

Mixtures are impure i.e. they have other components as well, eg, Lemon juice

CHARACTERISTIC 3:

Compounds are a result of Chemical Reactions

Mixtures can be prepared from simple mixing

CHARACTERISTIC 4:

Compounds posses constant composition

Mixtures have variable Composition

CHARACTERISTIC 5:

Compounds' components can not be separated easiy

Mixtures components can be separated easily with simple physical processes, eg, Heating of brine to get Salt and Water (Brine is a mixture isn't it)
