bond energy
A compound contain two or more elements associated by chemical bonds.
Chemical energy is energy stored in chemical bonds between atoms. Energy stored in fossil fuels is an example of potential energy.
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.
Activation energy is the energy needed to start a chemical reaction by breaking the existing chemical bonds in the reactants before new bonds can form in the products. This energy barrier must be overcome for the reaction to proceed.
Potassium and bromine form the ionic compound potassium bromide with the chemical formula KBr.
It is contained in the chemical bonds.
Chemical energy is stored in the bonds between atoms within a compound. These bonds contain potential energy that can be released through chemical reactions. The amount of energy stored depends on the type and arrangement of atoms in the compound.
It is contained in the chemical bonds.
Chemical energy is contained in the bonds between atoms within molecules. When these bonds are broken or rearranged during a chemical reaction, energy is released or absorbed. Examples include the energy stored in food molecules like glucose and in fossil fuels like gasoline.
It is contained in the chemical bonds.
Chemical energy is the energy stored in bonds between atoms in a compound. This energy is released or absorbed during chemical reactions.

Chemical changes involve breaking and forming of bonds between atoms. Chemical energy is required to break bonds. The formation of new bonds releases energy.
Forming bonds releases energy, whereas breaking bonds requires energy. When bonds are formed, energy is usually released in the form of heat. Conversely, when bonds are broken, energy is absorbed in order to break the chemical bonds.
This is referred to as "potential energy".
Energy stored in chemical bonds is released during cellular respiration
