WebIntroduction Nuclear energy. An absorption or release of nuclear energy occurs in nuclear reactions or radioactive decay; those that absorb energy are called endothermic reactions and those that release energy are exothermic reactions. Energy is consumed or released because of differences in the nuclear binding energy between the incoming … WebA reaction in which the only thing that happens is the breaking of a bond (for example the Cl–H bond in HCl) will always requires the input of energy. Acid-base reactions are typically exothermic; they release energy to the surroundings) and that released energy is associated with the interaction between the H+ and the base.
