Explanation
Hint: Magnesium nitride undergoes decomposition in water to give a pungent odor.
Explanation:
Mg reacts with N2 to form Mg3N2 .
Mg3N2 decomposes in water to form ammonia (having pungent odor) and magnesium hydroxide.
The equation of the reaction is:
Hence, the correct answer is option C.
Bromous acid HBrO_2 and Iodous acid HIO_2 and fluorous acid are not likely to exist in nature as they would decompose into oxides and water vapour when trying to isolate them from their respective acid solutions.
Hence, option B is correct.
Helium is used in balloons in place of hydrogen because it is incombustible. He do not catch fire like hydrogen. He is a inert element. Hence, option A is correct.
