Answer 1

Answer:

              Breaking chemical bonds requires energy and forming chemical bonds releases energy.

Explanation:

                        Bond Breaking is an endothermic reaction and requires energy. This energy provided to break the bond is called as bond energy. Hence, this is a non spontaneous reaction as it doesn't takes place on its own but requires energy to break them into smaller fragments.

                        While, Bond Forming is an exothermic reaction. When two substances come close together the formation of bond results in the release of energy. As the resulting product is stable hence, it will be lower in energy as compared to the sum of energies of the reactants. Therefore, the surplus energy is released in the form of heat.
