Atomisation energy Study guides, Class notes & Summaries

Lattice energy - - The enthalpy change when 1 mole of ionic compound is formed from its gaseous ions under standard conditions - It is the energy given out when ions of opposite charges comes together to form an ionic lattice Lattice energy is endothermic or exothermic? - - It is always exothermic because bonds are being formed (ionic bond) between oppositely charged ions, not broken Equation showing the formation of NaCl lattice - - Na^+(g) + Cl^-(g) > NaCl(s) The state of the opposite...

first ionization energy - The energy required to convert one mole of gaseous atoms into gaseous atoms with a single positive charge standard enthalpy of formation - the enthalpy change when 1 mole of a compound is formed from its elements in their standard states under standard conditions Standard Enthalpy of Atomisation - The enthalpy change when one mole of gaseous atoms is formed from an element in its standard state Lattice enthalpy - The enthalpy change that occurs when one mole of a ...

GRMN final examWhich 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 e...

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 ...
