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...

What are standard conditions? 298K/25°C 100kPa/1 atm 1 moldm-3 Enthalpy change of formation The enthalpy change when 1 mole of a compound is formed from its constituent elements under standard conditions, with all reactants and products in their standard states. Enthalpy change of combustion The enthalpy change when 1 mole of a substance is burned completely in oxygen. Enthalpy change of atomisation The enthalpy change that accompanies the formation of 1 mole of gaseous atoms from ...

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 ...
