To calculate the change in enthalpy during a chemical reaction, subtract the sum of the enthalpies of the reactants from the sum of the enthalpies of the products. This difference represents the change in enthalpy for the reaction.
The enthalpy of a chemical reaction is the change of heat during this reaction.
The enthalpy of a chemical reaction is the change of heat during this reaction.
the chemical shall be changed
