Multiple choice chemistry nitrogen and sulfur ammonia-properties and uses ammonia compounds of nitrogen - ammonia

Which of the following metal on burining in mosist air does not give smell of ammonia?

  1. $Mg$
  2. $Ca$
  3. $K$
  4. $Li$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Magnesium, calcium, and lithium react with atmospheric nitrogen when burned to form nitrides (Mg3N2, Ca3N2, Li3N), which release ammonia upon hydrolysis with moisture. Potassium is highly reactive but does not form a stable nitride under these conditions, so it does not produce ammonia.

The formula of Ammonium Sulphate is:

  1. $N{H} _{4}S{O} _{4}$
  2. ${(N{H} _{4})} _{2}S{O} _{4}$
  3. $N{H} _{4}{(S{O} _{4})} _{2}$
  4. $N{H} _{2}{(S{O} _{4})} _{2}$

B Correct answer
Explanation

Ammonium sulfate is made by treating ammonia, often as a by-product from coke oven, with sulfuric acid: 

$2 NH _3$ + $H _2SO _4 \rightarrow$   $(NH _4) _2SO _4$
Option "B" is correct.

Which of the following gives nitrogen on thermal decomposition?

  1. Ammonium nitrite

  2. Ammonia

  3. Ammonium dichromate

  4. Air
Reveal answer Fill a bubble to check yourself
A,B,C Correct answer
Explanation

Nitrogen gas is obtained by thermal decomposition of ammonium nitrite, ammonia and ammonium dichromate.

Ammonium dichromate on heating yields nitrogen, water and chromium(III) oxide and ammonium nitrate on heating yields nitrogen gas and water.

Nitriding is a process of heating steel in atmosphere of:

  1. $NH _{3}$
  2. $N _{2}$

  3. oxygen

  4. Carbon dioxide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Nitrating is a process of heating high carbon steels, aluminium, molybdenum etc in atmosphere of $NH _3$. Because of nitrating a case hardened surface of $N _2$ is formed on metal surface which comes from Ammonia.
