The answer is:
It will float
Slightly red in color is the only physical property
Explanation:
Nitrous oxide or dinitrogen monoxide can be simple be prepared by the decomposition of ammonium nitrate in the following way -
<u>The reaction is as follows -</u>
NH₄NO₃ ----------------> N₂O + H₂O
This is the unbalanced reaction as was asked in the question , without mentioning the states of matter .
The reaction is carried out in an anhydrous condition ,since , ammonium nitrate can explode on heating .
The initial report of the team formed by PURE may contain findings similar to the processes used in the disinfection of the water. Usual cases of ammonia presence in water are due to chloramine disinfection process. Also, they should also look into the storage of their facility and the end user which may also have a window of contamination.
