The term Energy is usually related to "force", however it can also be conceived as a natural resource that has the ability to transform something or put it in motion, human beings work and mold all these resources with scientific methods to create energy, resources Chemicals, which are the most abundant in the planet, are the ones that benefit most with chemical energy.
Everything that exists is matter and one of the qualities of matter is to possess chemical properties, and when two external bodies interact, a reaction occurs, altering its initial or natural state (this "alteration" is what is known as chemical energy).
In other words, chemical energy is nothing more than that type of energy that occurs as a consequence of a chemical reaction. For example, the combustion of wood or coal generates chemical energy. We can also say that it is always created, generated or produced from the interactions between atoms and molecules
On the other hand we also have that chemical energy is absorbed or detached by matter, an example of this are foods that comply with both processes, since they release energy in the form of calories, vitamins or proteins and our body processes and absorbs it.
One of the great advantages that chemical energy gives us is that it has an efficient use in different fields, one of them being the implementation of chemical energy in the elaboration of everyday products, such as cleaning articles, personal hygiene or the elaboration of medicines; It should also be borne in mind that this type of energy is what allows the mobilization of cars, planes and many machines in general, because this is a work produced within the engines and systems created for this purpose, and for these engines work they need fuel that once reacted will depend on the chemical energy so that it fulfills its function.
Chemical energy has a negative aspect since it causes serious damage to the environment creating pollution, waste and unusable and non-reusable material. This is because the materials used for their generation are toxic and harmful to health.
