Homolysis of a chemical bondA two-electron covalent bond is equally split when bond breaking, with each resulting fragment having one electron from the original shared pair. Notice that the products are free-radicals. The strength of bonds between different atoms varies across the periodic table and is well documented.

Answer 2

Answer:

When a chemical reaction occurs, molecular bonds are broken and other bonds are formed to make different molecules. For example, the bonds of two water molecules are broken to form hydrogen and oxygen.
