Answer 2

Answer:

Endothermic reactions are reactions that require external energy, usually in the form of heat, for the reaction to proceed. Since endothermic reactions draw in heat from their surroundings, they tend to cause their environments to cool down. Endothermic reactions generally involve the formation of chemical bonds through the absorption of heat from the surroundings.

Endothermic Reaction Examples

1. When ammonium chloride  is dissolved in water, an endothermic reaction takes place. The salt dissociates into ammonium  and chloride  ions.
2. The formation of nitric oxide from the reaction between nitrogen and oxygen
