Answer:
B
Explanation:
Technically none of them are completely correct, however the Professor likely just wants you to recognize that endothermic means absorbing heat which therefore means that the product should be hotter than than the reactants.
If you know that dissolving ammonium nitrate in water is an endothermic reaction, then you know that the temperature of the product is lower than the temperature of the reactants. The correct option is c.
The reaction which the heat is added to the object or increase the enthalpy of the system is called endothermic reaction.
As dissolving ammonium nitrate in water is an endothermic reaction, the heat will be added or temperature is increased after the reaction and products with increased enthalpy are obtained.
Therefore, dissolving ammonium nitrate in water is an endothermic reaction, then you know that the temperature of the product is lower than the temperature of the reactants. The correct option is c.
