it is equal to the difference of mass between the products and the reactants multiplied by the square of the speed of light in vaccum. (infact it is well apllicable to chemical reactions also where only small differences in masses are involved.)
NOTE:- the enery released or absorbed depends o whether the products are lighter ot heavier than the reactants.

It depends. There are two types of chemical reaction int his sense. Exothermic reactions release energy and endothermic reactions absorb it.
Exothermic reactions.
The binding energy of an atomic nucleus is the energy equivalent to the mass defect, which is the difference between the mass of the nucleus and the sum of the masses of its individual protons and neutrons. This energy is needed to hold the nucleus together and is released during nuclear reactions, such as fusion or fission.
An atomic bomb releases more energy than a conventional chemical bomb because the atomic bomb releases binding, or Nuclear Strong Force, energy while the conventional bomb releases chemical energy, and there is far more binding energy (hundreds and thousands of times) than there is chemical energy from the same mass of material.
nuclear energy
Energy from the tiniest particles of matter is called atomic or nuclear energy. This type of energy is released during nuclear reactions within the nucleus of atoms.
Nuclear Reaction.
The energy stored in an atomic nucleus is nuclear energy. This energy is released during nuclear reactions such as fission or fusion.
The type of nuclear reaction that releases energy through the combination of atomic nuclei is called fusion. This is different from fission reactions, which involve the splitting of atomic nuclei.
The source of atomic energy is the "binding energy" that exists in the nucleus of all atoms. This is the energy that is contained in the union of the protons and neutrons of the nucleus. When the nucleus is split apart, the binding energy is released.
The kind of energy associated with atomic bonds is chemical energy. This energy is released or absorbed when atoms form or break bonds with each other during chemical reactions.

Atomic energy is really a misnomer for nuclear energy. It is the fissioning of the nucleus which causes energy to be released. At the atomic level we are dealing with chemical reactions, but in the early days people did talk of atomic power and atomic bombs.
The potential energy in the nucleus of an atom is called nuclear potential energy. It is the energy associated with the interactions between protons and neutrons within the nucleus, which can be released in nuclear reactions such as fission or fusion.
A change in which energy is released is called an exothermic reaction. In exothermic reactions, energy is given off in the form of heat to the surroundings. This results in a decrease in the overall energy of the system.
The rest energy of hydrogen is important in nuclear reactions because it determines the amount of energy released or absorbed during the reaction. This energy is a key factor in understanding the stability and behavior of atomic nuclei.
