Types of Delta H

Postby ashwathinair » Sun Jan 26, 2020 4:46 pm

I know that delta H alone is a reaction's enthalpy and that delta Hf is standard enthalpy of formation, but in one of the homework problems (4D15) I came across delta Hc; does anybody know what this means?

I believe that’s heat capacity based on the units (:

the unit for delta Hf is kJ/mol, but for delta Hc I believe that the units are kJ/C, in which C represents a unit uniform throughout the problem

Delta Hc with the degree sign refers to the standard enthalpy of combustion.
