Amixture consists of sand and an aqueous salt solution. which can be used to seperate the same, salt, and water from each other

The process which can be used to separate salt from the sand is leaching since salt is soluble in water thus it goes to the water leaving the sand behind. To separate salt from the water, you can allow the water to evaporate where it undergoes a phase change.

The answer for this question is d. none of these

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
