Phosphorus pentasulfide is obtained by the reaction of liquid white phosphorus (P 4) with sulfur above 300 °C. The first synthesis of P 4 S 10 by Berzelius in 1843 [ 5 ] was by this method. Alternatively, P 4 S 10 can be formed by reacting elemental sulfur or pyrite , FeS 2 , with ferrophosphorus , a crude form of Fe 2 P (a byproduct of white ...
Potassium pentasulfide is the inorganic compound with the formula K 2 S 5.It is a red-orange solid that dissolves in water. The salt decomposes rapidly in air. It is ...
Like many sulfides, this compound liberates hydrogen sulfide upon treatment with strong acids such as hydrochloric acid. [3]6 HCl + Sb 2 S 5 → 2 SbCl 3 + 3 H 2 S + 2 S. Analysis by Mössbauer spectroscopy indicates that this compound is a derivative antimony(III), [4] explaining the production of antimony(III) chloride, rather than antimony(V) chloride, upon acidification.
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
6 These form water-stable salts. [12] The anion has an ethane-like structure and contains a P−P bond. The formal oxidation state of phosphorus is +4. The oxygen analogue is the hypodiphosphate anion, P 2 O 4− 6. P 3 S 3− 9 contains a six-membered P 3 S 3 ring. The ammonium salt is produced by reaction of P 4 S 10 in liquid ammonia. [13]
Bring your own empty water bottle and fill it up at the terminal, and pack your own snacks for the plane. “Snacks are more expensive than what you’d pay at a grocery store, so I always pack a ...
Leafy greens—like spinach, kale, collards, lettuce and cabbage—deliver fiber and water, meaning they'll help keep you hydrated and fill you up with lots of nutrients in a few calories.
