The H2 flammable and explosive gas is a nonmetallic material with 1 atom number H, the element symbol H, colorless, non-metallic, odorless, highly flammable, tasteless under normal temperature and pressure, is a biatomic gas found as H2 in its components in the east, the lightest gas known in the universe. It is 14.4 times lighter than air. Its mass is 1,00794g / mol, located in the upper left corner of the chemical periodic table, the H2 flammable and explosive gas is the most common gas element in the universe, which constitutes 75 percent of the mass of the known universe. The majority of the star group in the main star line visible to the telescopes is plasma In the world, there is very little in the form of hydrogen element, the H2 flammable and explosive gas used in the industry is obtained from mostly methane-like elements, but it is also a little expensive and it is obtained in the electrolysis of water.
The best-known natural isotope of hydrogen is a neutron free protium, H2 flammable and explosive gas is present in organic compounds as well as in many elements. Water also plays an important role in acid-base reactions as it dissolves, because it is the only neutral molecule in which it can be solved analytically, hydrogen atom is important in the development of quantum mechanics.
Although the H2 flammable and explosive gas was discovered in the 1500s, it was only in the 1700s that combustion could be understood. Hydrogen, the fuel source of solar and other star systems’ thermonuclear reaction, is the primary energy source of the universe, becomes liquid at -257.77C, the volume of liquid hydrogen is 1/700 times less than the volume of gas, for example a room full of the H2 flammable and explosive gas If it is brought to a degree, it can fill a small basin as a liquid. Hydrogen is the gas with the highest energy content per mass in known fuels.
H2 flammable and explosive gas was first separated by T. Von Hohenheim in 1493 and Paracelsus in 1521 by combining a few strong acids. It was not realized that this gas obtained as a result of the chemical reaction was flammable. When Henry Cavendish was burned by metal acid reaction in 1671, water, the air exploded by burning H2 flammable and explosive gas has realized that a separate element, the Cavendish hydrogen, mercury and acids have emerged with the emergence of many features, but in a realistic way, in 1783, the time of writing in modern science, the water that creates the water that is repeated burning water In the sense of strength is called hydrogen.
The H2 flammable and explosive gas was artificially created by mixing strong acids for the first time. It was thought that the gas obtained as a result of this chemical reaction was one of the units that initially formed the mercury, but the conversion to water refuted this thesis. The H2 flammable and explosive gas is first used in balloons and then zelplinler, hydrogen hydrogen iron and sulfuric acid reaction is obtained for these uses, hydrogen first flashes in the air with the result of the Zinlin called Hindenburg blown out of the Inet Helium was used instead.
