Question

Give an example of a chemical reaction in which a tremendous amount of heat is released.

Answer 1

Exothermic reaction:-

• An exothermic reaction is a type of reaction where heat(energy) is released.
• The energy which is released is in form of heat and light.
• An example of such a reaction is the reaction between powdered Aluminium with Iron(III) oxide, this reaction is also called a thermite reaction.
• The products formed here are Iron, Aluminium oxide, and an enormous amount of heat.

$\underset{\mathrm{Aluminium}}{2\mathrm{Al}\left(\mathrm{s}\right)}+\underset{\mathrm{Iron}\left(\mathrm{III}\right)\hspace{0.17em}\mathrm{oxide}}{{\mathrm{Fe}}_2{\mathrm{O}}_3\left(\mathrm{s}\right)}\to \underset{\mathrm{Iron}}{2\mathrm{Fe}\left(\mathrm{s}\right)}+\underset{\mathrm{Aluminium}\mathrm{oxide}}{{\mathrm{Al}}_2{\mathrm{O}}_3\left(\mathrm{s}\right)}+\mathrm{heat}$

Therefore, a chemical reaction in which a tremendous amount of heat is released is the explosion of an atom bomb.
