Question

When ammonia burns in oxygen, the products formed are _____ and water.

Answer 1

The reaction when ammonia $\left({\mathrm{NH}}_3\right)$ burns in oxygen $\left({\mathrm{O}}_2\right)$ will be:

• Four moles of ammonia reacts with five moles of oxygen to give four moles of nitric oxide $\left(\mathrm{NO}\right)$ and six moles of water vapors $\left({\mathrm{H}}_2\mathrm{O}\right)$.
• The reaction is exothermic is heat is released.
• $4{\mathrm{NH}}_3\left(\mathrm{g}\right)+5{\mathrm{O}}_2\left(\mathrm{g}\right)\stackrel{\text{Pt gaze}}{⟶}4\mathrm{NO}\left(\mathrm{g}\right)+6{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+\text{Heat}$

So, the final answer will be :-

When ammonia burns in oxygen, the products formed are Nitric oxide and water .
