Question

How is bond energy released?

Answer 1

Answer:

$\huge\mathbb\red{ANSWER}$

Breaking and making bonds

Energy is released when new bonds form. Bond-making is an exothermic process. Whether a reaction is endothermic or exothermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form.

Answer 2

Answer:

the energy released in forming new bonds minus the energy used in breaking the original bonds

Explanation:

The total energy input or output of a reaction equals the energy released in forming new bonds minus the energy used in breaking the original bonds. If it takes more energy to break the original bonds than is released when the new bonds are formed, then the net energy of the reaction is negative
