kinds of enthalpy

TermDefinition
Lattice enthalpy one mole of a solid ionic lattice is formed from its gaseous ions under standard conditions
enthalpy change of atomisation one mole of gaseous atoms is formed from its element in its standard states
ionisation energy one mole of gaseous 1+ ions is formed from gaseous atoms
electron affinity one mole of gaseous 1- ions is formed from gaseous atoms
hess' law if a reaction can take place by more than one route and the initial and final conditions are the same, the total enthalpy change is the same for each route
standard enthalpy chance of formation the enthalpy change that takes place when one mole of a compound is formed from its constituent elements in their standard states under standard conditions
combustion one mole of a substance undergoes complete combustion in oxygen with all substances in standard states
hydration one mole of gaseous ions become dissolved in water
solution 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
dissociation enthalpy change when one mole of covalent bonds is broken in the gaseous state

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.

To see how well you know the information, try the Quiz or Test activity.
