explain about the exothermic reaction
Answers
Answer:
An exothermic reaction is a chemical reaction that releases heat. It gives net energy to its surroundings.
Any process that rearranges the atoms of one or more substances to become a new substance is known as a chemical reaction. Chemical reactions are routinely completed in labs and occur as natural processes in the environment. Many chemical reactions absorb or release heat and energy as part of the process.
An exothermic reaction is any reaction that releases or gives off energy during the reaction. You can remember this by putting together 'exo-' which means to exit, with 'therm' which refers to heat. So a reaction where heat or energy leaves or is released is an exo-therm-ic reaction. (The opposite of an exothermic reaction is an endothermic one, where endo- means to absorb or let in energy.)
The energy given off can be in multiple forms, including heat, light, sound, or electricity. This energy is normally obtained as a result of bonds being broken during the reaction. In a molecule or compound, a majority of the energy is held in the bonds that link the molecules. Bonds have varying strengths. When a reaction occurs that causes these bonds to break, it gives off energy and is, therefore, exothermic.
