Ammonium nitrate is an important fertilizer with NPK rating 34-0-0 (34% nitrogen). [17] It is less concentrated than urea (46-0-0), giving ammonium nitrate a slight transportation disadvantage. Ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere.
Special factories were constructed for the manufacture of ammonium nitrate by the double decomposition of sodium nitrate and ammonium sulfate in solution followed by evaporative concentration and crystallization. It became the standard filling for shells and bombs, and was later adopted by the US as their principal high explosive. [3]
Upon detonation, TNT undergoes a decomposition equivalent to the reaction 2 C 7 H 5 N 3 O 6 → 3 N 2 + 5 H 2 + 12 CO + 2 C. plus some of the reactions H 2 + CO → H 2 O + C. and 2 CO → CO 2 + C. The reaction is exothermic but has a high activation energy in the gas phase (~62 kcal/mol).
The decomposition of ammonium nitrate is also a common laboratory method for preparing the gas. Equivalently, it can be obtained by heating a mixture of sodium nitrate and ammonium sulfate: [53] 2 NaNO 3 + (NH 4) 2 SO 4 → Na 2 SO 4 + 2 N 2 O + 4 H 2 O. Another method involves the reaction of urea, nitric acid and sulfuric acid: [54]
Ammonia has been used as fuel, and is a proposed alternative to fossil fuels and hydrogen. Being liquid at ambient temperature under its own vapour pressure and having high volumetric and gravimetric energy density, ammonia is considered a suitable carrier for hydrogen, [86] and may be cheaper than direct transport of liquid hydrogen. [87]
Adair, Iowa, had a population of 794. So, it seemed suspicious when its three-person police department asked regulators to buy 90 machine guns, including an M134 Gatling-style minigun capable of ...
Ammonia solutions decrease in density as the concentration of dissolved ammonia increases. At 15.6 °C (60.1 °F), the density of a saturated solution is 0.88 g/ml; it contains 35.6% ammonia by mass, 308 grams of ammonia per litre of solution, and has a molarity of approximately 18 mol /L.
Josh Stein’s victory in this year’s North Carolina governor’s race was huge. And his opponent was widely seen as the weakest Republican in a major race this cycle.
