Standard Enthalp
« on: November 15, 2007, 01:26:11 PM »
I wanted to make sure that all these have a standard enthalpy of formation value of zero:
Cl2 (g)
Fe (s)
Ne (g)
N (g)
Hg (l)

someone please correct me if i am wrong.

N (g) does not have a standard enthalpy of formation of 0. N2 (g) is 0.

Though, you can just looks these up in the table that you most likely have in the back of your book to verify yourself.
