Enthalpy and internal energy.

We know that enthaply is the study of heat released/absorbed in a chemical reaction and the physical changes related to it. But also that all objects in the universe have a preexisting energy called internal energy. Is there any correlation between enthalpy and internal energy?

Standard Reaction Enthalpies

Would Hess's law and other thermodynamic rules work if the equation isn’t in standard reaction enthalpies? If not what are the alternative methods.
