Does a exothermic reaction release energy
WebApr 10, 2024 · The heat of hydration is a reaction of cement with water that is exothermic, releasing a significant amount of heat. The heat release is further termed the heat of hydration. Hydration is a chemical reaction that occurs when the cement's major ingredients form chemical bonds with water molecules, producing hydrates or hydration products. WebUranium is produced from lead by a series of neutron captures, which release energy, and beta decays, which release energy; the free neutrons come from fusion reactions between alpha particles and moderate-mass nuclei, which release energy. All of the steps from lead to uranium are exothermic . How is it that an endothermic reaction can be made ...
