Symbols used on thermochemistry?

Postby jngao1J » Fri Jan 13, 2017 11:10 pm

I understand what most of the symbols mean so far, but what does the degree superscript mean when we write enthalphies? As in H(degree)(sub-f)

The degree superscript means that the enthalpy in question is a standard reaction enthalpy. H°f is the symbol for the standard enthalpy of formation.
