The chemical purpose of heating the MnSO4⋅H2O is to eliminate water with the formation of new compounds.
<h3>Dehydration reactions</h3>
Dehydration reaction is a type of chemical reaction that involves the removal of water which would eventually lead to the formation of a new compound.
The molecule of MnSO4⋅H2O contains a molecule of water(H2O). After heating of the molecule, water is lost giving rise to the dry compound MnSO4.
Other examples of dehydration reactions are:
- Reactions that produce acid anhydrides.
- Reactions that involve the production of polymers.
- Reaction of sucrose with concentrated sulfuric acid
Therefore, the chemical purpose of heating the MnSO4⋅H2O is to eliminate water with the formation of new compounds.

Answer: The correct answer is A
Explanation:
On addition of the ammonium nitrate to 50 ml of water the temperature decreases which means that reaction between the ammonium nitrate and water is an endothermic reaction.The value of
is positive for an endothermic reactions.

Entropy is a degree of randomness of the system.
On addition of the ammonium nitrate to water ammonium nitrate break down into ions which means that entropy is increased.

(Gibb's free energy)
Since, ammonium nitrate is getting dissolved in water which means that this reaction is spontaneous and
of spontaneous reaction is negative that is:

Control: skunk
Independent: poking (the skunk)
dependent: emission of toxic fumes
1.00mol is the correct answer
