In chemical reactions mass is doubled
WebThe change in the enthalpy of the system during a chemical reaction is equal to the change in its internal energy plus the change in the product of the pressure times the volume of the system. H = E + ( PV) Let's assume that the reaction is run in a styrofoam cup, as shown in the figure below.
