Answer
The hydration of anhydrous copper (II) sulfate is an is an ENDOTHERMIC reaction, also is a REVERSIBLE reaction, but it's not a NUCLEAR reaction.
Explanation
## Step1: Classification of Reactions Given that copper (II) sulfate is being hydrated (meaning it's reacting with water) to form a hydrate, this reaction falls under the category of chemical reactions. These aren't nuclear reactions, as nuclear reactions involve changes in the structure of an atom's nucleus. ## Step2: Endothermic or ExothermicAn endothermic process absorbs heat from its surroundings. When copper (II) sulfate reacts with water, it forms blue hydrates, and the reaction vessel can be seen to become warm when cold water is used. This is evidence that the reaction is absorbing heat from the environment to proceed, and so it can be classified as endothermic.## Step3: Reversible ReactionsReversible reactions are those where the products can react together to give back the reactants. In the case of copper (II) sulfate, it can be hydrated to give a hydrate (a product), and upon heating, the compound loses its water of crystallization and returns to its original anhydrous (no water) form, which is one of the reactants. Thus, we can also consider this reaction reversible.#
