Ammonium compounds are used not only for fertilisers, but also explosives. Billingham-on-Tees was a small village in 1917, when its Grange Farm was chosen to be the site of a large chemical works. On 22 March 1918, the Minister of Munitions approved the site to be developed as a factory that would make ammonium nitrate. [1]
Ammonium nitrate is a chemical compound with the formula NH 4 NO 3. It is a white crystalline salt consisting of ions of ammonium and nitrate . It is highly soluble in water and hygroscopic as a solid, but does not form hydrates .
The table above gives properties of the vapor–liquid equilibrium of anhydrous ammonia at various temperatures. The second column is vapor pressure in k Pa . The third column is the density of the liquid phase.
Chemical formula. NH 3 Molar mass: 17.031 g·mol −1 Appearance ... except under narrow fuel-to-air mixtures of 15–28% ammonia by volume in air. [40]
Lebanese authorities said 2,750 tonnes of ammonium nitrate had been stored for years at the Beirut port without safety measures. * Ammonium nitrate is an industrial chemical commonly used in ...
Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...
Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass (M r). [8] This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant .
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.
