Enthalpy change when a mole of electrons is added to a mole of gaseous ions each with a single negative charge
O- (g) + e- ==> O2- (g)
Enthalpy change when a mole of electrons is lost from one mole of singly positive charged ions
Na+ (g) ==> Na2+ (g) + e-
Enthalpy change when a mole of compound is formed from its elements under standard conditions and states
H2 (g) + 1/2 O2 (g) ==> H2O
Enthalpy change which accompanies formation of one mole of gaseous atoms from the element in its standard states and conditions
Mg (s) ==> Mg (g)
Enthalpy change when one mole of solute dissolves completely in sufficiently to form a solution where the molecules/ions are far enough apart not to interact
NaCl (s) + aq ==> Na+ (aq) + Cl- (aq)
Enthalpy change when one mole of solid ionic compound is formed from its gaseous ions
Na+ (g) + Cl- (g) ==> NaCl (s)
Enthalpy change when one mole of gaseous molecules each breaks a covalent bond to form two free radicals, averaged over a range of compounds
CH4 (g) ==> C (g) + 4H (g)
Enthalpy change when one mole of gaseous atoms are converted into a mole of gaseous ions with a single positive charge
Na (g) ==> Na+ (g) + e-
Enthalpy change when one mole of ionic compound separates into its gaseous ions
NaCl (s) ==> Na+ (g) + Cl- (g)
Enthalpy change when one mole of substance is completely burned in oxygen under standard conditions and standars states
CH4 (g) + 2 O2 (g) ==> CO2 (g) + 2H2O (l)
Enthalpy change when water molecules surround one mole of gaseous ions
Na+ + aq ==> Na+ (aq)
Enthalpy change when a mole of gaseous atoms are converted to a mole of gaseous ions each with single negative charge
O (g) + e- ==> O- (g)
