However, it is not commonly found in its pure form, since it readily combines with other elements. Hydrogen is easily ignited. It is also the lightest element, having a density of 0.08988 grams per liter at standard pressure.Hydrogen has several important chemical properties that affect its use as a fuel:If you would like to join the Connecticut Hydrogen-Fuel Cell Coalition, The material provided on the Connecticut Hydrogen-Fuel Cell Coalition website is intended for educational and informational purposes only. Hydrogen is the smallest chemical element because it consists of only one proton in its nucleus. It is flammable over a wide range of vapor/air concentrations. These applications will - due to browser restrictions - send data between your browser and our server. It was built, and is maintained, by the Pacific Northwest National Laboratory with funding from the DOE Office of Energy Efficiency and Renewable Energy's Hydrogen and Fuel Cell Technologies Office. Hydrogen is a colorless, odorless, tasteless, and nonpoisonous gas under normal conditions on Earth. Chemical, physical and thermal properties of hydrogen: Values at 25 o C (77 o F, 298 K) and atmospheric pressure It also shows the saturation pressure with changes in temperature. Once ignited it burns with a pale blue, almost invisible flame. We don't save this data.

Its symbol is H, and its atomic number is 1. All rights reserved. Hydrogen is the most abundant element in the universe, accounting for 90 percent of the universe by weight. It typically exists as a diatomic molecule, meaning each molecule has two atoms of hydrogen; this is why pure hydrogen is commonly expressed as “HHydrogen is the most abundant element in the universe, accounting for 90 percent of the universe by weight.

Hydrogen is the most abundant chemical substance in the universe, especially in stars and gas giant planets. It has a standard atomic weight of 1.008, meaning it is the lightest element in the periodic table.. Hydrogen is the most common chemical element in the Universe, making up 75% of all normal (baryonic) matter (by mass).Most stars are mostly hydrogen. It has an average atomic weight of 1.0079 amu, making it the lightest element. In petrol and diesel cars, the burning of fuel produces carbon dioxide and water. It has the symbol H and atomic number 1. Hydrogen Properties. The curve between the critical point and the triple point shows the hydrogen boiling point with changes in pressure.

Currently, there are a few zero-emission electric vehicles that can be powered by hydrogen. Physical Properties of Hydrogen. Properties Under the Energy Policy Act of 1992, hydrogen is classified as an alternative fuel. The phase diagram of hydrogen is shown below the table. Hydrogen is not toxic but is a simple asphyxiate by the displacement of Hydrogen is used to make other chemicals, in petroleum refining and in oxyhydrogen welding and cutting.Chemical, physical and thermal properties of hydrogen:Follow the links below to get values for the listed The hydrogen phase diagram shows the phase behavior with changes in temperature and pressure.
