Phosphorus cycles through the environment, changing form as it does so (Fig. Phosphorus pentoxide, which is the anhydride form of phosphoric acid (H 3 PO 4 ), has the empirical chemical formula P 2 O 5. Answer (1 of 2): Red phosphorous is just P. This is because- unlike white phosphorous which is made up of 4 P atoms per molecule- its structure is made 4. Animals get the organic phosphorus they need by eating either aquatic plants, other animals, or decomposing plant and animal material. When red phosphorus is heated in a sealed tube at 803K, an -black form is formed. In minerals, Phosphorus is found in the form of Phosphates. The molar mass of the oxide is 284g/mol. In clinical trials of Macrobid, the most frequent clinical adverse events that were reported as possibly or probably drug-related were nausea (8%), headache (6%): and flatulence (1.5%). It is stored under water. Phosphorus is added to a boiling mixture of phosphorus and trichloride, while a constant stream of chlorine is added to the reactor. White phosphorus occurs as discrete `P_4` units , where P atom lie at the corners of a regular tetrahedron . Phosphorus occurs in several allotropic forms, the most common of which are white phosphorus and red phosphorus (Fig 2). Red phosphorus is the most common allotrope of phosphorus. Approximately 2/3 of the ingested phosphorus is excreted in the urine, and the remaining 1/3 in stool and this phosphorus excretion is highly dependent on kidney function. The discovery of phosphorus dates back to 1669 by Hennig Brand.
Calcite and quartz may look the same in some regard to appearance but they are very different. The 32 P isotope is widely used in biology field as DNA or RNA probes.
