Identify the mixture of powdered chalk and
powdered table salt and suggest a technique
for separating their components.
1. homogeneous; dissolving followed by filtration and distillation
2. homogeneous; decanting
3. heterogeneous; decanting
4. homogeneous; distillation
5. heterogeneous; distillation

The correct answer is option 1.

Explanation:

The powdered chalk and the table salt both can make a homogeneous mixture in a water solution that can be separated with the help of two processes; filtration followed by the distillation.

The chalk powder dissolved in a solution of the salt and water can be separated with the help of the filter paper by the process of filtration.

The salt can be separated by the process of the distillation from the water or liquid and it remains as an extract.  

Thus, the correct answer is option 1.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
