Answer is: 2065.15 kJ.
Balanced chemical reaction: 4NH₃ + 5O₂ → 4NO + 6H₂O<span>, ΔHrxn=−906 kJ.
m(</span>NH₃) = 155 g.
n(NH₃) = m(NH₃) ÷ M(NH₃).
n(NH₃) = 155 g ÷ 17 g/mol.
n(NH₃) = 9.118 mol.
Make proportion: 4 mol(NH₃) : 906 kJ = 9.118 mol : Q.
Q = 906 kJ · 9.118 mol / 4 mol.
Q = 2065.15 kJ.
390 because im cool and awsome
The correct answer would be B for sure
