2 Na 2 HPO 4 + NaH 2 PO 4 → Na 5 P 3 O 10 + 2 H 2 O. Phosphorus pentoxide (P 4 O 10) is the acid anhydride of phosphoric acid, but several intermediates between the two are known. This waxy white solid reacts vigorously with water. With metal cations, phosphate forms a variety of salts. These solids are polymeric, featuring P-O-M linkages.
Phosphorus in the form of phosphates occur in compounds important to life, such as DNA and ATP. Humans consume approximately 1 g of phosphorus per day. [25] Phosphorus is found in foods such as fish, liver, turkey, chicken, and eggs. Phosphate deficiency is a problem known as hypophosphatemia. A typical 70 kg human contains 480 g of phosphorus ...
Phosphorus in the lower of its two most common oxidation states, P(III) (e.g., phosphorous acid, phosphorous anhydride) A common misspelling of the element name ...
BSc meteorologist Janice Davila tells Bored Panda that one of the most unknown facts from her field of expertise is that weather radars are slightly tilted upward in a half-degree (1/2°) angle.
Along with nitrogen and potassium, phosphorus is an essential ingredient for fertilizers. Fertilizers have played a key part in the Green Revolution, which has helped feed an extra 4.2.
Phosphorus condenses to a liquid below about 280°C and then solidifies (to the white phosphorus allotrope) below about 44°C (depending on purity). This same essential reaction is still used today (but with mined phosphate ores, coke for carbon, and electric furnaces). Brand's process yielded far less phosphorus than it could have.
White phosphorus, yellow phosphorus or simply tetraphosphorus (P 4) exists as molecules of four phosphorus atoms in a tetrahedral structure, joined by six phosphorus—phosphorus single bonds. [1] The free P 4 molecule in the gas phase has a P-P bond length of r g = 2.1994(3) Å as was determined by gas electron diffraction . [ 2 ]
A U.S.-led military coalition also deployed white phosphorus weapons in Syria and Iraq in its war against ISIS in 2017, according to HRW. Israel, too, previously used the substance during a 2008 ...
