Question

a mixture has different concentration of particles throughout
a)homogeneous
b)hetrogeneous​

Answer 1

A homogeneous mixture has the same proportions of its components throughout any given sample and is also referred to as a solution. Conversely, a heterogeneous mixture has components in which proportions vary throughout the sample.

Answer 2

A mixture has a different concentration of particles throughout in HETEROGENOUS solution. (OPTION B)

HETEROGENEOUS SOLUTION -

• A solution composed of two or more phases forming separate layers.
• The composition is not uniform and the components will not be completely mixed.
• The components can be separated from each other by physical means as individual components retain their chemical identity.
• The phases in the mixture are at least two solids, liquids, or gases, or a suspension, emulsion, aerosol, colloids, or smoke.
• Example -

1. Oil and water

2. Orange juice containing pulp and fibers in water.

3. Sandy water

4. Soil is made of mud, sand, stones, clay.
