Question

Chlorine reacts with excess of ammonia to form:
A. Hydrochloric acid and hypochlorous acid
B. Nitrogen oxide and nitric oxide
C. Hydrogen and oxygen
D. Ammonium chloride and nitrogen

Answer 1

Hint: First we should be aware of the reaction taking place which is regarding the chlorine and ammonia gas where the concentration of ammonia is in excess ( in order to stabilize the conditions ). Now we can say that here if they will react mildly then there would be excretion of nitrogen gas along with ammonium chloride due to chloride formation.

Complete answer:
Here in the given question statement the question is regarding the ultimate products that will form on the subsequent reaction of the chlorine and ammonia. In the given circumstances we have to deal with the reaction that will take place.
Now, in this question the ammonia is mentioned in excess amount in comparison to the amount of chlorine gas present.
Pure chlorine gas at an imaginative comparison with the ideal conditions has the tendency to react vigorously with ammonia gas. We can also say that if there is an excessive mix of the two gases in the air then, it has the capability of producing hazardous compounds like the explosive nitrogen trichloride gas.
Whereas when ammonia is in excess amount, the reaction would be :
\[3C{l_2} + 8N{H_3} \to 6N{H_4}Cl + {N_2}(g)\]

So, the correct option is option D.

Note: Chlorine gas poisoning is an illness resulting from the effects of exposure to chlorine beyond the threshold limit value. The signs of acute chlorine gas poisoning are primarily respiratory, and include difficulty breathing and cough; listening to the lungs will generally reveal crackles. There will generally be sneezing, nose irritation, burning sensations, and throat irritations.
