please include correct units included, correct number of significant digits. 

Using the following reactions, calculate the heat of the first reaction.
Note: all three enthalpies are negative
4NH3(g) + 5O2(g) → 4NO(g) + 6H₂O(g)
N2(g) + O2(g) →→ 2NO(g)
N2(g) + 3H₂(g) → 2NH³(g)
H₂(g) + ½ O2(g) → H₂O(g)
ΔΗ = ???
AH=180.5kJ
AH 91.8kJ
AH=241.8kJ
