what is the state of oxygen difluoride at –200 °c

The reaction requires heat, irradiation, or an electrical discharge. [1] Dioxygen difluoride reacts vigorously with nearly every chemical it encounters – even ordinary ice – leading to its onomatopoeic nickname "FOOF" (a play on its chemical structure and its explosive tendencies). OXYGEN DIFLUORIDE is an oxidizing agent. It can exist as an orange-colored solid which melts into a red liquid at −163 °C. They have excellent chemical resistance and thermal stability. Solidoxygen O2, like liquid oxygen, is a clear substa… Fluorine being the most electronegative element (electro negativity of 4.0 on Pauling scale) will in any case (except in fluorine gas) have an oxidation state of -1. [4][5] The modern preparation entails the reaction of fluorine with a dilute aqueous solution of sodium hydroxide, with sodium fluoride as a side-product: Its powerful oxidizing properties are suggested by the oxidation number of +2 for the oxygen atom instead of its normal −2. Can explode on contact with water.Decomposes to toxic gaseous fluorine if heated to high temperature. Dioxygen difluoride reacts vigorously with nearly every … Oxygen difluoride is a chemical compound with the formula OF2. Even at a temperature of −160 Â°C (113 K), 4% decomposes each day[1] by this process: The other main property of this unstable compound is its oxidizing power, although most experimental reactions have been conducted near −100 Â°C (173 K). Synthesis proceeds by the simple formula Xe + F2 → XeF2. It is a very powerful oxidizing agent. Mixtures with carbon monoxide, with hydrogen, or with methane explode on sparking [Streng, A. G., Chem. Oxygen difluoride is a central oxygen with two lone pairs and two single bonds to fluorine at less than 109.5 degrees. Oxygen difluoride exhibits divisibility. Despite its instability, thermochemical data for O2F2 have been compiled.[8]. Some of the compounds that produced violent reactions with O2F2 include ethyl alcohol, methane, ammonia, and even water ice. A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. Textbook solution for Chemistry & Chemical Reactivity 9th Edition John C. Kotz Chapter 2.8 Problem 1RC. § means the substance has not been made. While OF2 would be a solid at 30 K, the fictional alien lifeforms were described as endothermic, maintaining elevated body temperatures and liquid OF2 blood by radiothermal heating. Home Oxygen difluoride exhibits the following properties. OF2 reacts with many metals to yield oxides and fluorides. Nonmetals also react: phosphorus reacts with OF 2 to form PF 5 and POF 3 ; sulfur gives SO 2 and SF 4 ; and unusually for a noble gas , xenon reacts, yielding XeF 4 and xenon oxyfluorides. Dioxygen difluoride can be obtained by subjecting a 1:1 mixture of gaseous fluorine and oxygen at low pressure (7–17 mmHg is optimal) to an electric discharge of 25–30 mA at 2.1–2.4 kV. Although oxygen is a colorless, odorless, tasteless gas that is non-combustible, it's not completely benign in all situations. Dioxygen difluoride is a compound of fluorine and oxygen with the molecular formula O2F2. For Hydronium Ion, H3O+ Give The Following Information: A.) The synthesis of XeF2 was first reported by Weeks, Cherwick, and Matheson of Argonne National Laboratory in 1962. The carbon atoms in the chemical structure of Oxygen difluoride are implied to be lo… Images of the chemical structure of Oxygen difluoride are given below: The 2D chemical structure image of Oxygen difluoride is also called skeletal formula, which is the standard notation for organic molecules. This is proved by the oxidation number of +2 for the oxygen atom. Room temperature is roughly 23C so it would be a gas. In Robert L. Forward's science fiction novel Camelot 30K, oxygen difluoride was used as a biochemical solvent by fictional life forms living in the solar system's Kuiper belt. It can exist as an orange-colored solid which melts into a red liquid at −163 Â°C (110 K). OF 2 reacts with many metals to yield oxides and fluorides .
