  2. Ammonium nitrate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_nitrate

    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.

  3. Thermal decomposition - Wikipedia

    en.wikipedia.org/wiki/Thermal_decomposition

    Thermal decomposition, or thermolysis, is a chemical decomposition of a substance caused by heat. ... Ammonium nitrate on strong heating yields dinitrogen oxide ...

    All are thermally unstable towards decomposition to their elements. One other possible oxide that has not yet been synthesised is oxatetrazole (N 4 O), an aromatic ring. [15] Nitrous oxide (N 2 O), better known as laughing gas, is made by thermal decomposition of molten ammonium nitrate at 250 °C. This is a redox reaction and thus nitric oxide ...

  6. Nitrous oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide

    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]

    All are thermally unstable towards decomposition to their elements. One other possible oxide that has not yet been synthesised is oxatetrazole (N 4 O), an aromatic ring. [66] Nitrous oxide (N 2 O), better known as laughing gas, is made by thermal decomposition of molten ammonium nitrate at 250 °C. This is a redox reaction and thus nitric oxide ...

  8. Ammonium nitrite - Wikipedia

    en.wikipedia.org/wiki/Ammonium_nitrite

    Ammonium nitrite forms naturally in the air and can be prepared by the absorption of equal parts nitrogen dioxide and nitric oxide in aqueous ammonia. [1]It can also be synthesized by oxidizing ammonia with ozone or hydrogen peroxide, or in a precipitation reaction of barium or lead nitrite with ammonium sulfate, or silver nitrite with ammonium chloride, or ammonium perchlorate with potassium ...

  9. Enthalpy change of solution - Wikipedia

    en.wikipedia.org/wiki/Enthalpy_change_of_solution

    Dissolving ammonium nitrate in water is endothermic. The energy released by the solvation of the ammonium ions and nitrate ions is less than the energy absorbed in breaking up the ammonium nitrate ionic lattice and the attractions between water molecules.
