log 10 of anydrous ammonia vapor pressure. Uses formula shown below. Vapor-pressure formula for ammonia: [4] log 10 P = A – B / (T − C),
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 ...
In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +
The rate constant, k, of this reaction depends on the temperature of the environment, with a value of at 10 K. [179] The rate constant was calculated from the formula = (/) . For the primary formation reaction, a = 1.05 × 10 −6 and B = −0.47 .
UAN is a solution of urea and ammonium nitrate in water used as a fertilizer.The combination of urea and ammonium nitrate has an extremely low critical relative humidity (18% at 30 °C) and can therefore only be used in liquid fertilizers.
[7] [8] A US liquid gallon can contain about 3.785 kilograms or 8.34 pounds of water at 3.98 °C (39.16 °F), and is about 16.7% less than the imperial gallon. There are four quarts in a gallon, two pints in a quart and 16 US fluid ounces in a US pint, which makes the US fluid ounce equal to 1 / 128 of a US gallon.
Many folks opt to aim for the nice, square number of 1 gallon of water a day (for reference, 2.7 liters equal about 0.7 gallons), so we looked into the health benefits of drinking that much H20 ...
Ammonium sulfate is made by treating ammonia with sulfuric acid: 2 NH 3 + H 2 SO 4 → (NH 4) 2 SO 4. A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2% to 4% of free sulfuric acid at 60 °C.
