Question

Give one example of an endothermic reaction

Answer 1

1. The chemical reactions which occurs by absorption of heat are called endothermic reactions.
2. Example: Melting of ice cubes.

Melting solid salts.

$$\begin{gathered} {\mathrm{N}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)+\mathrm{heat}\to 2\mathrm{NO}\left(\mathrm{g}\right) \\ \left(\mathrm{Nitrogen}\right)\left(\mathrm{Oxygen}\right)(\mathrm{Nitric}\mathrm{oxide}) \end{gathered}$$.
