Can someone explain the main difference between enthalpy and the change in internal energy?

Enthalpy is just the heat absorbed or released during a reaction and you can just consider the internal energy as just the sum of all of the total energy contained in the system.

internal energy includes heat and work. sometimes change in internal energy is equal to change in enthalpy, and this happens when you are at constant pressure and volume.

Enthalpy is the heat absorbed/released while internal energy is just the total amount of energy.

Enthalpy is specifically the energy absorbed/released, so its only going to be equal to internal energy at a constant pressure and volume.
