Question

What is called an exothermic reaction? Give examples ​

Answer 1

Answer:

An exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones. ... Most of the spectacular chemical reactions that are demonstrated in classrooms are exothermic and exergonic.

Examples: Carbon burns in oxygen to form carbon dioxide and heat energy is produced. C + O2 → CO2 + Heat.
