mixtures can be separated using a variety of methods, such as evaporation (seen in the image). what mixture could be separated using this method?
a) water and ice
b) salt and water
c) sand and pebbles
d) sand and iron filings

salt and water

Explanation:

Water and ice isn’t a mixture it’s the same substance in another form. If you evaporate salt and water it separates the solvent from the solute. If you were to evaporate the mixture in a cup you would see white resadu from the salt.

Option (B) is the correct answer.

Explanation:

A mixture is defined as a substance in which two or more components are physically combined but none of the components are chemically combined to each other.

For example, sand and pebbles is a heterogeneous  mixture.

Components of a mixture can be separated by physical means.

On the other hand, when solute particles are evenly distributed in a solvent then this type of mixture is known as homogeneous mixture.

For example, salt in water is a homogeneous mixture.

This mixture can be easily separated through evaporation.

Thus, we can conclude that salt and water mixture could be separated using evaporation method.
