Hess law states that enthalpy of the reaction is equal enthalpy of products minus enthalpy of reagents.

Thank you for the advice. Enthalpy of Al(OH)3 is not found in any site in internet. If anybody has the answer to my question for this reaction AlF3 (l) + 3H2O (g)→ Al(OH)3 (l) + 3HF (g) kindly give. Whatever guidance provided by earlier replies did not help.

Googling for "Aluminum hydroxide enthalpy of formation" got me the answer in no time.
joyabraham:
Does anybody know if this is an exothermic or endothermic reaction?
Orcio_87:
True, but joyabraham asks for a liquid (melted) AlF3 and Al(OH)3, so this requires additional data to find (heat capacities and enthalpies of melting).
