Given the following data NH3(g) → > N₂(g) + ³H₂(g) 2H₂(g) + O₂(g) →→ 2H₂O(g) calculate AH for the reaction ΔΗ = 46 kJ ΔΗ = -484 kJ 2N₂(g) + 6H₂O(g) →→30₂(g) + 4NH3(g)

Use and modify some/all the reactions provided to form the indicated overall reaction according to Hess' Law. • If a reaction is not used in your Hess' Law process, include that indication by multiplying the reaction by "0" • If no modification is needed and the reaction is applied as written below, include that indication by multiplying the reaction by "1" • Use whole numbers and simple fractions (such as "2" or "1/2", not 0.5) and negative signs (such as "-2") where needed Then calculate and report the enthalpy change (in kJ) for the overall reaction in the indicated blank, including units with your written value and rounded to 1 decimal place.
