Answer: Option (a) is the correct answer.

Step-by-step explanation:

A homogeneous mixture is defined as a mixture that contains evenly distributed solute particles into the solvent.

For example, NaCl dissolved in water is a homogeneous solution.

On the other hand, a solution in which solute particles are not evenly distributed into the solvent is known as a heterogeneous mixture.

For example, when sand is added to water then it forms a heterogeneous solution.

Thus, we can conclude that for both homogeneous and heterogeneous mixtures the composition vary.

Answer:

Option a. both homogeneous and heterogeneous mixture.

Step-by-step explanation:

This can be explained as a mixture is the combination of more than one substances mixed together while retaining their identities or chemical properties.

  • Homogeneous mixtures in which the components are mixed in the same amounts or proportion, i.e., it has uniformity in it.
  • Heterogeneous mixtures in which the constituents are not mixed in uniform proportion and are separable.
  • Pure elements are those which have the a stable isotope or the atomic number of which are same.
  • Thus the composition can only vary in homogeneous and heterogeneous mixtures.
