Definition of lattice enthalpy. The enthalpy change that accompanies the formation of one mole of an ionic compound from its gaseous ions in standard conditions.
Hess' law definition If a reaction can take place via multiple paths and the conditions at the start and finish are the same the the overall enthalpy change will be the same for each route.
Standard enthalpy change of formation definition. The change in enthalpy when 1 mole of a compound is formed from its constituent elements in their standard states under standard conditions.
Enthalpy change of atomisation definition. Enthalpy change when one mole of gaseous atoms forms from the element in its standard state.
1st ionistaion energy definition the energy required to release one mole of electrons from one mole of atoms in gaseous form to produce a 1- ion.
1st electron affinity the enthalpy change when an electron is added to mole mole of gaseous atoms to produce a 1+ ion.
definition for the enthalpy change of combustion. the enthalpy change when 1 mole of a substance undergoes combustion in the presence of o2 with all substances in standard states.
Hydration enthalpy defintion enthalpy change when 1 mole of gaseous ions become dissolved in water (hydrated).
enthalpy of solution. enthalpy change when one mole of an ionic solid dissolves in an amount of water large enough so that the dissolved ions are well separated and do not interact with each other.
Bond dissociation enthalpy enthalpy change when 1 mole of a covelant bond is broken in the gaseous state.
lattice enthalpy of dissociation. enthalpy change when one mole of a solid ionic compound is broken up into its constituent ions in thegas phase.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
