Question

Explain compound and a mixture with a suitable example.

Answer 1

Answer:

A compound is made up of two or more elements in definite proportion. Eg : H2O is water which has the ratio of hydrogen : oxygen as 8:1

A mixture is also made up of two or more elements but they are not in definite proportion. Eg: salt in water, sand in water, milk, collidal solutions

Answer 2

$\mathcal{\huge{\fbox{\pink{Mixture:-}}}}$

Mixtures are heterogeneous forms of matter. Mixtures are composed of variable proportions of molecules and atoms.

The Properties of Mixtures :-

• The composition of a mixture is variable.
• Each of its components retains its characteristic properties.
• Its components are easily separated.

Example :-

• Soil
• Air

$\mathcal{\huge{\fbox{\purple{Compound:-}}}}$

Compounds are homogeneous forms of matter. Their constituent elements (atoms and/or ions) are always present in fixed proportions.

The Properties of Compounds :-

• The relative proportions of the elements in a compound are fixed.
• The components of a compound do not retain their individual properties. Both sodium and chlorine are poisonous; their compound, table salt (NaCl) is absolutely essential to life.
• It takes large inputs of energy to separate the components of a compound.

Example :-

• Water (H2O)
• Table salt (NaCl)
