WebThe released energy performs work or causes physical and chemical changes. It is obvious that the amount of energy released in a chemical reaction is related to the amount of reactants. For example, when the amount is doubled, so is the amount of energy released. 2 H 2 ( g) + O 2 → 2 H 2 O ( l), d H = − 571.6 k J / m o l. Web10 de out. de 2024 · In this post, we’ll focus on chemical energy and how it can be converted into light energy. Chemical energy is stored in the bonds between atoms in molecules. When those bonds are broken, chemical energy is released and can be used to do work. One way to convert chemical energy into light energy is through a process …
