Sagot :
to break a chemical bond, energy must be absorbed. Energy is released and new bonds are formed
Energy must be [tex]\boxed{{\text{supplied}}}[/tex] in order to break a chemical bond.
Further explanation:
A chemical bond is defined as the attraction between atoms and molecules that leads to the formation of different chemical compounds. Such bonds are formed either by electron sharing or by electron transference between the atoms. The bond that results from the transfer of electrons is called ionic bond while that formed due to sharing of electrons is called the covalent bond.
Endothermic process
The processes that require energy from the surroundings (usually in the form of heat) are known as endothermic processes. Examples of such processes include photosynthesis, evaporation of water, and melting of ice.
Exothermic process
The processes that release energy from the system to the surroundings (generally in the form of heat) are called exothermic reactions. Examples of exothermic reactions include the combustion of fuels, nuclear reactions, and neutralization reactions.
The breaking of a chemical bond is an endothermic reaction so energy must be supplied to the system from the external surroundings.
