the elements in a fluorine-bomb calorimeterThe standard molar enthalpy of formation of liquid hydrogen fluoride ΔfHom (HF, l) = -(303.56 ± 0.27) kJ·mol-1 at T = 298.15 K and po = 101.325 kPa has been measured by direct reaction of gaseous hydrogen and fluorine in a bomb calorimeter...
• Standard Enthalpy of Formation is “The change in enthalpy that accompanies the formation of 1 mole of a compound from its elements with all substances at standard state.” •We envision taking elements at their standard state,and combining them to make compounds,also at standard state. ...
