Bond enthalpy equation of hi

WebHydrogen iodide (H I) is a diatomic molecule and hydrogen halide. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid.Hydrogen iodide and hydroiodic acid are, however, different in that the former is a gas under standard conditions, whereas the other is an aqueous solution of the gas.They are interconvertible. WebJan 30, 2024 · ΔH = 4 (413) + 2 (498) - 2 (805) - 2 (41) - 4 (464) ΔH = -900 kJ mol -1. The measured enthalpy change of combustion is -890 kJ mol -1, and so this answer agrees to within about 1%. As bond enthalpy calculations go, that's a pretty good estimate. The standard enthalpy change of neutralization is the enthalpy change …
