delta vs. delta naught
What is the difference between delta G, H, and S versus delta G naught, H naught, and S naught?

Re: delta vs. delta naught
The naught simply indicates that the values of G, H, and S are measured at STP conditions (1 atm and 273 K).

Re: delta vs. delta naught
The difference between the two is that delta G naught is at standard conditions. The reason Professor Lavelle emphasized it is because delta G naught is always the same because it is referring to when the reactants/products are at standard temperature/pressure. As the rxn goes towards equilibrium, delta G (without the naught) changes because the rxn is proceeding. So as the chemical rxn approaches equilibrium, delta G (without the naught) approaches zero. However, delta G naught remains the same because it is still referring to when the rxn is at standard conditions. I hope that helped!
