Question

what is endothermic reaction? example
​

Answer 1

Explanation:

An endothermic reaction is any chemical reaction that absorbs heat from its environment. The absorbed energy provides the activation energy for the reaction to occur. ... A good example of an endothermic reaction includes dissolving a salt. It doesn't have to be table salt, nor does the solvent need to be water.

Answer 2

$\huge\colorbox{violet}{❥︎Answer}$

Endothermic reactions are reactions that require external energy, usually in the form of heat, for the reaction to proceed.As such, the change in enthalpy for an endothermic reaction is always positive. In order to melt the ice cube, heat is required, so the process is endothermic.
