Use the following information: [[[[2H2(g) + O2(g) → 2H2O(l) ∆H = −572 kJ mol−1]]]] [[[[2H2(g) + O2(g) → 2H2O(g) ∆H = −484 kJ mol−1]]]] to calculate the enthalpy change for the process: H2O(g) → H2O(l)

Well the method I use for calculations in thermochemistry is a little different from the textbooks but is far easier to understand. 

I would approach this question by drawing out the chemical equat...
