Ammonium nitrate is___________________?
Correct answer: C. Mixed with limestone powder to reduce its explosive nature before using it as a fertilizer
- A. Having about 40% N2
- B. Not hygroscopic
- C. Mixed with limestone powder to reduce its explosive nature before using it as a fertilizer
- D. Not prone to explosive thermal decomposition
Explanation
Ammonium nitrate contains about 34.5% nitrogen, is hygroscopic, and can undergo explosive thermal decomposition. Mixing it with limestone reduces its effective concentration and explosive hazard for fertiliser use.
