Hydrogen - Element information, properties and uses
WitrynaHydrogen is the first element in the periodic table and has the atomic number one. Those elements which have the same atomic number but a different mass number are called isotopes. There are three isotopes of hydrogen namely, protium 1 1 H, deuterium 2 1 H or D and lastly tritium 3 1 H or T. The isotopes are different because of the … Hydrogen forms a vast array of compounds with carbon called the ... various heavy radioactive isotopes were given their own names, but such names are no longer used, except for deuterium and tritium. The symbols D and T ... Typically the cathode is made from platinum or another inert metal when … Zobacz więcej Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula H2. It is colorless Zobacz więcej Discovery and use In 1671, Robert Boyle discovered and described the reaction between iron filings and dilute acids, which results in the production of hydrogen gas. Having provided a saline spirit [hydrochloric … Zobacz więcej H2 is produced in chemistry and biology laboratories, often as a by-product of other reactions; in industry for the hydrogenation of Zobacz więcej H2 is a product of some types of anaerobic metabolism and is produced by several microorganisms, usually via reactions catalyzed by iron- or nickel-containing enzymes called hydrogenases. These enzymes catalyze the reversible redox reaction … Zobacz więcej Combustion Hydrogen gas (dihydrogen or molecular hydrogen) is highly flammable: 2 H2(g) + O2(g) → 2 H2O(l) (572 kJ/2 mol = 286 kJ/mol = … Zobacz więcej Hydrogen, as atomic H, is the most abundant chemical element in the universe, making up 75 percent of normal matter by mass and more than 90 percent by number of atoms. … Zobacz więcej Petrochemical industry Large quantities of H2 are used in the "upgrading" of fossil fuels. Key consumers of H2 include hydrodealkylation, hydrodesulfurization, and hydrocracking. Many of these reactions can be classified as Zobacz więcej WitrynaAnother benefit of using molten salts for the cogeneration of hydrogen with nuclear power plants is the ability of the molten salts to absorb tritium. Tritium is a radioactive form of hydrogen that can diffuse through hot metals; thus, the reactor design must be chosen to minimize the amount of tritium entering the hydrogen production facility ... blood red lips lyrics
