Cold Fluorine Gas
Fluorine
Moissan discovered fluorine in 1886. It is a chemical element with the symbol F, atomic number 9, 9 electrons and protons, 10 neutrons, and the atomic mass of 19. Being the lightest halogen, it has one stable isotope, fluorine19. At standard pressure and temperature, the element is a pale yellow gas as a liquid its a bright yellow. The electrons are located outside the nucleus of the atom. Electrons are organized in such a way that the space between them are inter dispersed. Within this space are distinct distances up to 100,00 times away from the nucleus of the atom. Reactions with fluorine are often sudden or explosive. Many substances are generally regarded as unreactive such as powdered steel, glass fragments, and asbestos fibers. Asbestos fibers are readily consumed by cold fluorine gas. Wood and even water will burn with flames when subjected to a jet of fluorine, without the need for a spark. Fluorine will melt at -219.6 C and boil at -188 C. Fluorine is added to city water supplies in the proportion of about one part per million to help prevent tooth decay. Sodium fluoride (NaF), stannous (II) fluoride (SnF2) and sodium mono fluorophosphates (Na2PO3F) all fluorine compounds added to toothpaste, also to help prevent tooth decay. Fluorine is found in nature in the form of calcium fluoride, called fluorite, which forms regular crystals. California has many fluorite deposits. There are also deposits in Alaska and Argentina Fluorine is the most electronegative and reactive of all elements. Until World War II, there was no commercial production of elemental fluorine. The nuclear bomb project and nuclear energy. Applications, however, made it necessary to produce large quantities. Fluorine and its compounds are used in producing uranium (from the hexafluoride) and more than 100 commercial fluorochemicals, including many high-temperature plastics. Hydrofluoric acid is used to etch light bulbs and other glass. Fluorochlorohydrocarbons are extensively

    Polymers are large macromolecules composed of many small repeating subunits (monomers) connected via covalent bonds. Both natural and synthetic polymers are created via polymerization of these small molecules (Chemistry 144 Writing Assignment information sheet).

    ¬¬The goal of the first part of this experiment was to achieve a 50-50 conversion of fluorene to Fluorenone. In order to achieve the goal of the experiment fluorene was oxidized to Fluorenone. The hydroxide ions from the sodium hydroxide in the presence of Stark’s catalyst would be able to de-protonate the acidic fluorene protons. This would result in the formation of a carbanion which attacks the oxygen from the air resulting in the formation of a hydroperoxide and eventually a ketone (after removal of water). Since the goal was to have a mixture of 50% fluorene conversion, Thin Layer Chromatography (TLC) was carried out several times to assess the rate of the reaction. In order to separate the aqueous composites from the solution…

    To determine the cation of the compound, a cation flame test was performed. A bunsen burner was lit until a medium blue flame was burning. The given unknown was scooped onto a nichrome wire loop. The wire was held in the flame to determine the cation. To compare the unknown’s flame color to a known cation’s flame color, a sample of known compound were taken to perform a flame test. The cation barium burned a pale green color at a low intensity. The cation calcium…

    Even from its discovery atomic research has been filled with doubt and danger where every massive breakthrough has resulted in fear its potential. The radioactive age began in 1869 when Wilhelm Roentgen discovered X-rays, being the first practical application of a radioactive invention. (Silverstein, 31) In 1898, the Curies discovered the element of Radium and from then on America would never be the same. Radium found its way into paint, candles, and eye washes. In 1938; however, Otto Hahn-a German chemist and physicist-fired neutrons at uranium atoms and succeeded in splitting an atom for the first time, this event would ultimately change the entire course of human…

    Our data revealed that unknown number one was lithium chloride because of the very similar dark red color of the flame. We determined the second unknown to be strontium chloride because both flames gave off a similar bright red color. The third unknown’s flame had a very distinct salmon color, identical to the flame of potassium chloride. And the fourth unknown was barium chloride because both flames burned bright, neon…

    The purpose of this experiment is to conduct different experiments that will illustrate the different gas laws. We will be given a list of equipment need to perform the experiment as well as general rules to help us do the experiment. We will investigate three properties of gases pressure, temperature, and volume. By doing this experiment we will be able to define the gas laws. According to Boyles, it states that a fixed amount of ideal gas that is kept at a fixed temperature, that the pressure and volume are inversely proportional, if the temperature stays unchanged. According to Charless Law, if the pressure of a gas is held constant, as the gas is heated, its volume will increase and that cooling the gas will cause the volume to decrease. Charles law describes that of the Gay- Lussacs law, who had actually referenced unpublished work of Charles. The law states that at a constant pressure, the volume of the given mass of the ideal gas will increase/ decrease, the same ways as the temperature will increase/ decrease. An easier way to interpret this is that at a constant pressure, volume and temperature are directly proportional. Materials Lab quest Vernier gas pressure sensor Temperature probe 20 mL gas syringe 125 mL Erlenmeyer flask 3 600mL beakers hot plate Dry ice rubber stopper with 2-way valve Procedure and observations (Part 1) The first thing we did in this experiment was measure pressure and volume. To do this we used the lab quest and syringe. You attach the syringe to the valve of the gas pressure sensor. We pick a volume and when reading the volume on the syringe make sure you read from the inside black ring on the piston of the syringe. Make sure to connect the gas pressure sensor to the Lab Quest and choose new from the file menu. Then you will set up the data collection, first change the collection mode to events with entry, then enter volume and units (mL) and select ok. When collecting the data allow for the pressure to fluctuate and when it is…

    Otto Hahn was a German chemist who revolutionized the field of nuclear chemistry. Following a lifelong interest in chemistry, he found himself on the forefront of radiochemistry research in the early 20th century. Through a series of chance discoveries, he and his fellow researchers brought radiochemistry out of the realm of theoretical research and into actual practical science. One of the practical uses of this research led to the development of nuclear weapons. While Otto Hahn’s lifetime of education and research led to great contributions to chemistry, it also led to his dedication to using his powerful voice for social causes, especially to limit the threat of nuclear weapons.…
