<h3>
How do chemical reactions occur?</h3>
The transformation that takes place in substances, wherein atoms rearrange themselves and alter their initial state, is what gives rise to chemical processes. As a result, chemical compounds alter and produce new molecules.
A replacement reaction is the sort of reaction implied by the chemical formula Ca + MgCl2 --- CaCl2 + Mg.
In this instance, energy is absorbed during the chemical reaction to break bonds in the reactants and build bonds in the products.
