Which of the following has a standard enthalpy of formation value of zero at 25 degrees C and 1.0 atm
and what is enthalpy or how do you find it
All elements have a delta Hf of zero at 1.0 atm and 25o C.
So I need to find the Hf of each of those equations
All ELEMENTS have a standard heat of formation of zero at 1.0 atom and 25 degrees C. Which of the 5 answers listed is an ELEMENT (the other four are, of course, compounds).
Fe(s) is an element right
