Nitrous oxide is prepared on an industrial scale by careful heating of ammonium nitrate at about 250 C, which decomposes into nitrous oxide and water vapour. The addition of various phosphate salts favours formation of a purer gas at slightly lower temperatures.
The pneumatic trough removes the water from the reaction as well as smoke from impurities in the ammonium nitrate. The gas in the collection jar is your nitrous oxide or laughing gas, plus lesser amounts of other nitrogen oxides, including nitric oxide or nitrogen monoxide.

N₂O. It is prepared by heating ammonium nitrate
NH₄NO₃ --(Δ)--> N₂O + 2 H₂O
Hope it helps you !!
