What is Enthalpy?
I usually that term for explain system's heat.
I know enthalpy and heat is not exactly same......but I really dont know what is difference of these terms and when could I use the term 'Entalpy' and 'heat' and when can I regard heat or enthalpy as enthalpy or heat.
and PLEASE USE EXAMPLE. (1) Examples of cases that Q and H are the same (2) Examples of cases that Q and H are different
please distinguish them as sharp as knife.

Given 2Al2O3 (s) --> 4Al(s) + 3O2 (g) (standard enthalpy change= 3351.4 kJ) a) What is the heat of formation of aluminum oxide
Given 2Al2O3 (s) --> 4Al(s) + 3O2 (g) (standard enthalpy change= 3351.4 kJ) a) What is the heat of formation of aluminum oxide? How do I find heat of formation from standard enthalpy change? I know how to do it when I'm given enthalpy, but they aren't the same thing- correct? Also, if this question gave me delta-H, I know that the heat of formation for 4Al = 0 and 3O2 = 0 because they are elementary species. This would...
