Energy and Chemical
font size:SmallMiddleBig

Chemical energy is a new type of energy. Various energy can be formed due to the energy formed by the reaction of atoms and substances in the molecule. It can be defined as the energy generated by the rearrangement of electron forces, charges, electrons and protons in the process of aggregation In , the positional arrangement of the two sides is very important, so it is basically the charge of electrostatic potential energy. If chemical energy is reduced in a chemical reaction system, it will be transferred to the environment formed in some form (usually heat or light). on the other hand. If the system increases chemical energy due to a chemical reaction, then the heat provided in the environment is either removed in the form of light (usually again differentially). E.g. When two hydrogen atoms react to form a dihydrogen molecule, such as 724 Océ [H bond energy-H bond] chemical energy decreases: When the electron completely removes the hydrogen atom, a hydrogen ion is formed [in: gas phase), 2.18 Oxel chemical energy increase (the ionization energy of hydrogen)

A very common quotation is 1 mole, depending on the essence of the problem: the typical value of the chemical energy change in moles. The chemical energy change in a chemical reaction ranges from tens to hundreds of kilojoules per mole. According to the above definition, chemical energy can be viewed as: When it comes to internal energy, it is technically the constant quantity that keeps the system calculated: chemical energy. However, the most practical chemical energy is done under constant pressure. If the volume changes during the reaction (eg gas giving off), it must be corrected. Enthalpy is obtained from the work done in the atmosphere.
