hydrogengas
Hydrogengas, or hydrogen gas, is the diatomic gaseous form of the element hydrogen. Its chemical formula is H2, consisting of two covalently bonded hydrogen atoms. It is colorless, odorless, and tasteless, with an extremely low density—about 0.0899 kg per cubic meter at standard conditions, roughly 14 times lighter than air. Hydrogen has the highest energy content per unit mass of any fuel, but its energy per volume is low unless compressed or liquefied. It is the most abundant element in the universe but on Earth is mostly found bound in compounds.
Industrial production of hydrogen is dominated by steam methane reforming, which converts natural gas to H2
Applications include refining, petrochemical processing, ammonia synthesis, methanol production, and hydrogenation reactions. It is a common
Safety and handling: hydrogen is highly flammable and forms explosive mixtures with air over a wide concentration
