Endothermic
ATP
the change in the nuclei of the atoms.
Energy is released in an exothermic reaction because bonds are being formed.
The release of Energy
The bonds in a molecule can break and atoms can bond with other atoms.
During chemical reactions bonds are broken.
Chemical bonds are both formed and broken during chemical reactions. For example, bonds are formed and broken in the synthesis reaction 2H2 + O2 = 2H2O. The bonds in both diatomic oxygen and hydrogen are broken, forming new bonds to form a water molecule.
CHEMICAL Chemical energy is stored in the bonds between atoms. This stored energy is released and absorbed when bonds are broken and new bonds are formed - chemical reactions. Chemical reactions change the way atoms are arranged. These reactions both absorb and release energy, but the net reaction releases energy.
This is a chemical reaction.
chemical bonds between atoms
Chemical bonds are broken.
Chemical reactions can be either endothermic (that is, where bonds broken) or exothermic (i.e. where bonds are formed). The former requires thermal energy input; the latter releases heat energy as bonds are formed.
in chemical reactions, energy is absorbed or released when chemical bonds are broken and new ones are formed.
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
A chemical reaction in which bonds are broken is usually associated with the release of energy. Stable bonds are responsible for releasing energy as they are formed.
