what is the name of the compound formed from iron,phospherous,hydrogen and oxygen? |
Iron forms such compounds as oxides, hydroxides, halides, acetates, carbonates, sulfides, nitrates, sulfates, and a number of complex ions. It is chemically active and forms two major series of chemical compounds, the bivalent iron (II), or ferrous, compounds and the trivalent iron (III), or ferric, compounds. Ferrous sulfate heptahydrate, FeSO4·7H2O, sometimes called green vitriol, is a compound formed by the reaction of dilute sulfuric acid (formerly called oil of vitriol) with metallic iron; it is used in the manufacture of ink, in dyeing, and as a disinfectant. Ferric chloride hexahydrate, FeCl3·6H2O, is a yellow-brown crystalline compound used as a mordant in dyeing and as an etching compound. Ferric oxide, Fe2O3, is a reddish-brown powder used as a paint pigment and in abrasive rouges. Prussian blue, KFe2(CN)6, is a pigment containing the ferrocyanide complex ion. Iron rusts readily in moist air, forming a complex mixture of compounds that is mostly a ferrous-ferric oxide with the composition Fe3O4. Phosphorus In compounds of phosphorus (where known), the most common oxidation numbers of phosphorus are: 5, 3, and -3. Hydrides The term hydride is used to indicate compounds of the type MxHy and not necessarily to indicate that any compounds listed behave as hydrides chemically. Phosphine: PH3 Diphosphorus tetrahydride: P2H4 Fluorides Phosphorus trifluoride: PF3 Phosphorus pentafluoride: PF5 Diphosphorus tetrafluoride: P2F4 Chlorides Phosphorus trichloride: PCl3 Phosphorus pentachloride: PCl5 Diphosphorus tetrachloride: P2Cl4 Bromides Phosphorus pentabromide: PBr5 Diphosphorus tetrabromide: P2Br4 Iodides Phosphorus triiodide: PI3 Diphosphorus tetraiodide: P2I4 Oxides Tetraphosphorus decaoxide: P4O10 Tetraphosphorus hexaoxide: P4O6 Sulfides Tetraphosphorus trisulphide: P4S3 Tetraphosphorus decasulphide: P4S10 Tetraphosphorus hexasulphide: P4S6 Tetraphosphorus nonasulphide: P4S9 Tetraphosphorus pentasulphide (alpha): P4S5 Tetraphosphorus heptasulphide: P4S7 Tetraphosphorus tetrasulphide: P4S4 Selenides Tetraphosphorus triselenide: P4Se3 Hydrogen The term hydride is used in a generic sense to indicate compounds of the type MxHy and not necessarily to indicate that any compounds listed behave chemically as hydrides. In compounds of hydrogen (where known), the most common oxidation numbers of hydrogen are: 1, and -1. Hydrides The term hydride is used to indicate compounds of the type MxHy and not necessarily to indicate that any compounds listed behave as hydrides chemically. Fluorides Hydrogen fluoride: HF Chlorides Hydrogen chloride: HCl Bromides Hydrogen bromide: HBr Iodides Hydrogen iodide: HI Oxides Water: H2O Sulfides Hydrogen persulphide: H2S2 Hydrogen sulphide: H2S Selenides Hydrogen selenide: H2Se Tellurides Hydrogen telluride: H2Te Nitrides Ammonia: NH3 Hydrazine: H2NNH2 Oxygen Oxygen is one of the most active of all chemical elements. The oxygen-oxygen bond in diatomic oxygen is relatively strong, but once broken, the atomic oxygen formed (O) reacts readily with the vast majority of elements. The noble gases and noble metals are the most important exceptions, although oxy compounds of most of these elements are also known and can be prepared by indirect methods. The reaction between oxygen and another element generally results in the formation of a binary compound known as an oxide. The reaction itself is known as oxidation. For example, the oxidation reaction between oxygen and sodium produces sodium oxide. In many cases, an element may form more than one oxide. Copper, as an example, forms both copper(I) (cuprous) oxide and copper(II) (cupric) oxide. Nitrogen forms five oxides: nitrous oxide (N2O), nitric oxide (NO), dinitrogen trioxide (N2O3), nitrogen dioxide (NO2), and dinitrogen pentoxide (N2O5). Perhaps the most important of all oxides is water, by far the most abundant compound on the planet. Water is composed of two hydrogen atoms bonded to a single oxygen atom by means of a strong covalent bond. |
