If energy was added (endothermic change) to remove the water from the salt, then what would happen energetically if water was added to the anhydrous salt? Explain

Answer with Explanation:

If water will be added to the anhydrous salt, a backward reaction will occur. This will result to the process of "solvation."

Solvation occurs when the solvent molecules interact with the solute molecules. In the situation above, the solute is the "anhydrous salt" while the solvent is the water.

"Like dissolves like" means that the polarity of salt will allow it to be dissolved in water, which is also polar. The binding of the anhydrous salt ions to water molecules releases lots of energy, which is more than the energy absorbed during the endothermic process. Such process of giving off energy is exothermic in nature.

So, this explains the answer.

i think it is true since you can test the answer and can use observations to complete it.
