Calculate the heat of formation (∆Hf) of water (H2O) given the following reactions and their respective heats of reaction (∆Hr):2H2(g) + O2(g) → 2H2O(g); ∆Hr = -484 kJ/mol ½ O2(g) + H2(g) → H2O(l); ∆Hr = -285.8 kJ/mol Note: The heat of formation is the amount of heat released or absorbed when one mole of a compound is formed from its elements in their standard states.
