During any chemical reaction, heat can be either taken in from the environment or released out into it. The heat exchange between a chemical reaction and its environment is known as the enthalpy of reaction, or H. However, H can't be measured directly — instead, scientists use the change in the temperature of a reaction over time time to find the change in enthalpy over time (denoted as ∆H). With ∆H, a scientist can determine whether a reaction gives off heat (or "is exothermic") or takes in heat (or "is endothermic"). In general, ∆H = m x s x ∆T, where m is the mass of the reactants, s is the specific heat of the product, and ∆T is the change in temperature from the reaction.….….….….….…...
