Properties of H2

Sum and Difference Rules of Differentiation

The percentage by mass of each element present in a compound is defined as Percentage Composition. It is calculated from the molecular formula by dividing the mass of a single element in one mole of a compound by the mass of one mole of that compound. The value is defined or expressed as a percentage..

Spectrum of Hydrogen Atom

An electric discharge produces excited hydrogen atoms, which dissociate hydrogen molecules and excite the atoms. These atoms emit light at specific wavelengths, some of which fall within the visible spectrum. In a spectrograph, visible light is dispersed by a diffraction grating and detected by photographic film. The wavelength controls the position of the lines in

Some Important Reactions of Heavy Water

Heavy water is a form of water in which deuterium is incorporated instead of protium. Hydrogen has three isotopes mainly- protium, deuterium, and tritium. Therefore, heavy water differs from some normal water in properties.  These changes in properties are due to the change in the number of ions. For example, deuterium naturally found in water

Semi Heavy Water (HDO)

Regular water is composed of two protium isotopes of hydrogen and oxygen. Semi water contains one protium and one deuterium in its composition. It should not be confused with heavy water, where two deuterium hydrogen isotopes are mixed with oxygen. Isotopes Of Hydrogen And Water Hydrogen mainly contains three isotopes – protium, deuterium, and tritium.

Role of Promoters in Haber’s Process

Haber’s Process is also regarded as Haber’s Bosch Process. It is a process by which atmospheric nitrogen is converted into ammonia. This process is mainly used in industries for large scale production of ammonia. This process is named after German Chemists Fritz Haber and Carl Bosch. In 1913 first time ammonia was manufactured using this

Properties of Hydrogen

Hydrogen is normally found as a diatomic molecule. This means it has two hydrogen atoms in each molecule, which is why pure hydrogen is denoted as ‘H2’. Hydrogen is a diatomic molecule-forming element. Diatomic molecules are made up of two atoms of the same element. They usually exist because the element is too reactive to
