During chemical reactions
WebAug 8, 2024 · When a chemical reaction occurs, the atoms in the reactants rearrange their chemical bonds to make products. The new arrangement of bonds does not have the same total energy as the bonds in the reactants. Therefore, when chemical reactions occur, there will always be an accompanying energy change. WebFeb 15, 2024 · Simply put, a chemical reaction is any transformation from one set of chemicals into another set. If the starting and ending substances are the same, a change …
