Here are some ways to describe exothermic reactions in chemical terms:
* Heat-releasing reaction: This is a simple and direct description.
* Negative enthalpy change reaction: Enthalpy (H) is a thermodynamic property that represents the total energy of a system. In an exothermic reaction, the enthalpy of the products is lower than the enthalpy of the reactants, resulting in a negative enthalpy change (ΔH < 0).
Remember, "exothermic" is a general term describing the energy flow, not a specific chemical name.
