Exothermic reaction
Neither
exothermic
The dissolution is endothermic.
endothermic but don't know why? As AN crystals are formed the reaction is exothermic. Endothermic when it melts back with water. This is the reason AN is used in cold packs.
It is not a chemical reaction, it is dissolution; this physical process is exothermic.

H2O + Na2SO4 = Exothermic reaction
This is a strong exothermic reaction.
exothermic
The reaction is very exothermic.
Endothermic
The dissolution is endothermic.

The reaction between calcium and water is very exothermic.
It is small, but overall endothermic.
Gas devolve reactions are exothermic. So it is a exothermic too.
