Clues

  • The enthalpy change that accompanies the formation of one mole of an ionic compound from it's gaseous ions, under standard conditions. (7, 8)
  • The enthalpy change when one mole of a compound is formed from it's constituent elements under standard conditions, all elements being in their standard states. (8, 2, 9)
  • The enthalpy change when one mole of an ionic solid dissolves in enough water, so the dissolved ions are well separated, and do not react with one another. (8, 2, 8)
  • The enthalpy change when one mole of gaseous ions becomes hydrated. (8, 2, 9)
  • This states that if a reaction can take place by more than one route, and the starting and ending conditions are the same, then the total enthalpy change is the same for both routes. (4, 3)
