May 5, 2024 · In 1929 Karl Friedrich Bonhoeffer, a German physical chemist, and Paul Harteck, an Austrian chemist, on the basis of earlier theoretical work, showed that ordinary hydrogen is a mixture of two kinds of molecules, ortho-hydrogen and para-hydrogen. Because of the simple structure of hydrogen, its properties can be theoretically calculated ...
Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H2, sometimes called dihydrogen, [11] but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen. It is colorless, odorless, tasteless, [12] non-toxic, and ...

It has the lowest density of all gases. Uses. Some see hydrogen gas as the clean fuel of the future – generated from water and returning to water when it is oxidised. Hydrogen-powered fuel cells are increasingly being seen as ‘pollution-free’ sources of energy and are now being used in some buses and cars.
This is common in interstitial/metallic hydrides. The first four of these possibilities are summarized in Scheme 8.4.1.I. Scheme 8.4.1.I. Common bonding arrangements for hydrogen. The E-H and E---E bonds in the bridging hydride represent sharing of two or more electrons among the three atoms. Figure 8.4.1.1 ).

Jul 7, 2020 · Disadvantages of hydrogen as a fuel: 1. Isolating pure hydrogen in a massive scale is quite expensive. 2. Storage and transport of hydrogen is problematic. 3. It is quite expensive than the commonly used fuels. 4. Hydrogen is highly inflammable .Thus to use hydrogen as a fuel is quite risky.
Ammonia synthesis is the most significant use of hydrogen. A large amount of hydrogen is consumed in the catalytic hydrogenation of vegetable oils to extract solid fat. It is also consumed as rocket fuel when combined with oxygen, and as a rocket propellant by nuclear energy. Hydrogen is burnt as a fuel to burn in internal combustion engines.
