Molar mass: 17.031 g·mol −1 Appearance Colourless gas Odor: ... Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the formula N H 3.
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.
Standard molar entropy, S o liquid? J/(mol K) Heat capacity, c p: 80.80 J/(mol K) Gas properties Std enthalpy change ... log 10 of anydrous ammonia vapor pressure.
The B−N distance is 1.58(2) Å. The B−H and N−H distances are 1.15 and 0.96 Å, respectively. Its similarity to ethane is tenuous since ammonia borane is a solid and ethane is a gas: their melting points differing by 284 °C. This difference is consistent with the highly polar nature of ammonia borane.
Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +.It is formed by the addition of a proton (a hydrogen nucleus) to ammonia (NH 3).
Ammonium fluoride sublimes when heated—a property common among ammonium salts. In the sublimation, the salt decomposes to ammonia and hydrogen fluoride; the two gases can still recombine, i.e. the reaction is reversible: [NH 4]F ⇌ NH 3 + HF
If you’re stuck on today’s Wordle answer, we’re here to help—but beware of spoilers for Wordle 1326 ahead. Let's start with a few hints.
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 ...
