energy
It depends on the reaction. An exothermic reaction releases (liberates) energy and an endothermic reaction absorbs energy.
the heat released or absorbed in a reaction
energy released by the reaction or energy absorbed.
endothermic reaction
Endothermic, if the energy is in the form of heat.
endothermic
Energy.

In a chemical reaction, energy can be both absorbed and released. When energy is absorbed, it is required to break bonds in the reactants, and when it is released, it is due to the formation of new bonds in the products. Additionally, atoms and molecules can also be absorbed and released in various forms during a chemical reaction.
Depending on the particular chemical reaction, energy may be either released or absorbed.
Endothermic. This means that heat is absorbed from the surroundings, resulting in a decrease in temperature.
