Question

define homogeneous and heterogeneous mixtures. ​

Answer 1

Homogeneous Mixture

These are the types of mixtures in which the components mixed are uniformly distributed throughout the mixture. In other words, “they are uniform throughout”. We can observe only one phase of matter in a homogeneous mixture.

Key points regarding such mixtures are:

-Particles are distributed uniformly

-We can’t judge a homogeneous mixture by just seeing it

-Homogeneous mixtures are also called as solutions

-Uniform composition

-Example: rainwater, vinegar, etc.

Heterogeneous Mixture

This is a type of mixture in which all the components are completely mixed and all the particles can be seen under a microscope. We can easily identify the components and more than one phase can be seen by naked eyes.

Key points regarding this type of mixtures:

-Particles are distributed non uniformly

-We can judge a heterogeneous mixture by just seeing it

-Non-uniform composition

-Example: seawater, pizza, etc.

Answer 2

$answer$

Homogeneous mixtures:-

They have same composition throughout the mixture.

They can not be separated by physical methods.

EXAMPLE :-

Water

Heterogeneous mixtures:-

They do not have same composition throughout.

They can be separated by physical methods.

EXAMPLE:-

Mixture of iron nails and sand.
