Question

Exothermic and Endothermic reactions. give examples from Nature​

Answer 1

Endothermic Reaction Examples. ... These ions go on to form ammonium hydroxide (NH4OH) and nitric acid (HNO3) respectively (by reacting with the OH– and H+ ions in water). This reaction is endothermic in nature since it cools the surroundings by absorbing heat from it.

A nuclear explosion is an example of a (highly) exothermic reaction.

Answer :-

1.Exothermic reactions: Those reactions in which energy is released in the form of heat are called exothermic reactions.

Examples :-

(1) All combustion reactions e.g.

CH4 + 2O2 —> CO2 + 2H2O + Heat

(2) Thermite reactions e.g.

2Al + Fe2O3 —> 2Fe + Al2O3 + Heat

Combinations are generally exothermic in nature. The decomposition of organic matters into compost is an example of exothermic reaction.

2.Endothermic reactions: Those reactions in which energy is absorbed are called endothermic reactions.
