Atomisation energy - Study guides, Class notes & Summaries

Which of the following is not one of Ian Kershaw's conclusions in his essay "Hitler's Power and Destruction"? A) There is nothing that stands as a positive artistic legacy of Hitler's reign. B) No governmental form or system which could serve as a possible model emerged from the Nazi regime. C) Hitler's final escape plan, thwarted by the Allies, reveals the inner flaws of his strategic and tactical thinking. D) Devoid of constructive, creative energy, articulating only ever wilder urge...

Standard enthalpy of formation correct answer: enthalpy change when it is made from the stable form of its elements at standard condition combustion enthalpy correct answer: exothermic, so always negative atomisation enthalpy correct answer: endothermic, so always positive ∆H(rxn)= correct answer: ∑∆Hºf(products) - ∑∆Hºf(reactants) standard enthalpy of formation correct answer: change of enthalpy during the formation of one mole of the substance from its constituent ...
