WebEnthalpy Changes. The total chemical energy inside a substance is called the enthalpy (or heat content) When chemical reactions take place, changes in chemical energy take place and therefore the enthalpy changes. An enthalpy change is represented by the symbol Δ H (Δ= change; H = enthalpy) An enthalpy change can be positive or negative. WebIt includes the balanced chemical reaction and the change in enthalpy value. 2. When manipulating thermochemical equations, if I divide the coefficients of the chemical …
