When ammonia reacts with hydrogen chloride gas, it produces white fume

1.	When ammonia reacts with hydrogen chloride gas, it produces white fumes of ammonium chloride. The volume occupied by NH_(3) in glass bulb A is three times more than the volume occupied by HCl in glass bulb B at STP. (i) How many moles of of ammonia are present in glass bulb A? (ii) How many grams of NH_(4)Cl will be formed when the stopper is opened? ("Atomic mass of N = 14, H = 1, Cl = 35.5") (iii) Which gas will remain after completion of the reaction? (iv) Write the chemical reaction involved in this process.
Answer» Solution :(i) `"Capacity of "NH_(3)" bulb = 67.2 litre"` `"22.4 litre of "NH_(3)="1 mole"` `therefore"67.2 litre of "NH_(3)=(1)/(22.4)xx67.2="3 moles of "NH_(3)` (ii)`{:("Atomic MASS of 1(N)"=1xx14,=,14g),("Atomic mass of 4(H)"=4xx1,=," 4g"),("Atomic mass of 1(Cl)"=1xx35.5,=,35.5g),(,,""ulbar("53.5g")):}` `"Mass of "NH_(4)Cl=53.5g` (iii) `NH_(3)` (Ammonia) gas will remain after the completion of the reaction. (iv) Chemical equation of the reaction `underset("Ammonia")(NH_(3))+underset("Hydrochloric ACID")(HCl)RARR underset("CHLORIDE")underset("Ammonium")(NH_(4)Cl)`
