Energy can be stored. Energy is stored in chemicals, with the amount of energy stored depending on the energy contained within the chemical bonds. Energy is conserved. During a chemical reaction, energy is conserved. This means that energy cannot be destroyed or created: it can ...14. Endothermic reactions require energy input to proceed, meaning their products have more energy than their reactants. In contrast, exothermic reactions release energy, ending with products having less energy than the reactants. Both endothermic and exothermic reactions are under constant study in chemistry for energy management.

An endothermic process may be a chemical process, such as dissolving ammonium nitrate ( NH4NO3) in water ( H2O ), or a physical process, such as the melting of ice cubes. The opposite of an endothermic process is an exothermic process, one that releases or "gives out" energy, usually in the form of heat and sometimes as electrical energy.Jul 30, 2017 · The main difference between endothermic and exothermic reactions is that endothermic reactions absorb energy from the surrounding whereas exothermic reactions release energy to the surrounding. Each and every chemical reaction can be grouped into these two categories by calculating the enthalpy change in the reaction. References: 1 ...
