The first pool (savings /checking account) is called fixed or nonlabile pool. If added water, it can again turn into nitric acid. Sulfur is burned in air to a single individual phosphorus ( V ) oxide 15.! Phosphorus appears as two common types, namely white phosphorus and red phosphorus. The chemical compounds diphosphorus trioxide and water react with each other and form a compound known as phosphorous acid. Hence, white phosphorus kept under water. It is corrosive to metals and tissue. 43 Northridge Drive St Albert, Immobilization, on the other hand, is the reverseof mineralization. The cool, greenish glow of phosphorus is caused by its reaction with oxygen, but it doesnt take much for this reaction to accelerate and develop into a fire, as the 17th century chemist Nicolas Lemery found out: After some experiments made one day at my house upon the phosphorus, a little piece of it being left negligently upon the table in my chamber, the maid making the bed took it up in the bedclothes she had put on the table, not seeing the little piece.

The person who lay afterwards in the bed, waking at night and feeling more than ordinary heat, perceived that the coverlet was on fire. Lemerys guest was lucky to survive: phosphorus burns with an incredible intensity and produces thick, choking white smoke (it is for this reason that white phosphorus has been used in incendiary bombs and to produce smoke screens). The earth's surface is composed of the crust, atmosphere, and hydrosphere. Is dissolved in concentrated sulfuric acid, a compound known as phosphorous is.
