A chemical reaction involves the breaking up of chemical bonds between atoms resulting in the -------- and simultaneously the formation of bonds with the ----------

Answer:

A chemical reaction involves the breaking up of chemical bonds between atoms resulting in the absorption of energy and simultaneously the formation of bonds with the release of energy.

Chemical reaction

A chemical reaction is in which the bonds are broken within reactant molecules, and new bonds are formed within product molecules in order to form a new substance. It is usually accompanied by a release of energy when a chemical bond is broken. Likewise, an input of energy is needed for the formation of chemical bonds. The supplied/released energy can come in different ways, such as heat, light, and electricity.

Endothermic reactions

In general, endothermic reactions include the formation of chemical bonds by heat absorption from the surroundings.

Examples: 

  • The melting of ice to form water.
  • The baking of bread

Exothermic reactions

The release of heat energy produced from bond-breakage involves exothermic reactions.

Examples:

Generally referred to as burning, combustion is an exothermic reaction wherein, when exposed to an oxidizing agent, a fuel undergoes reduction and becomes an oxidized substance.
