By definition, chemical reactions are those that cause the chemical bonds between atoms to break and reorganize, giving rise to different substances.
<h3>Substances present in a chemical reaction</h3>
In a chemical reaction there are the substances that react, that is, the reactants, and the substances produced, called products.
<h3>Mass of a chemical reaction</h3>
The mass of the participating substances is the same before and after the reaction, that is, it is conserved. This happens because only a rearrangement takes place between the atoms of the reactants, which break and form new bonds.
<h3>Energy necessary of a chemical reaction</h3>
It must be taken into account that for a chemical reaction to occur the reactants must collide since energy is necessary to break the chemical bonds between atoms.
<h3>Summary</h3>
In summary, chemical reaction is the way one substance reacts against another. In this way, the chemical bonds between atoms are broken and new bonds are formed.
