important uses of hydrogen

Importance of Radio Waves in Modern Communication - Radio waves are electromagnetic waves of wavelength 10 - 3 m and higher. Their frequency range is from a few kHz to nearly a few hundred MHz. The propagation of radio waves through the atmosphere is relevant in all modern forms of commun..

1. Most widely used amorphous solids are inorganic glasses, used as construction material houseware laboratoryware etc. 2. Another important material is rubber used in making tyres. Amorphous silica has been found to be the best material ..

i) Required for solubilization of chemicals and several biochemical reactions like hydrolytic digestion of polymeric nutrients, photosynthesis, etc. ii) Important for the working of macromolecules, as a good ionizer, transport of materials, etc. iii) Acts as a habitat for hydropyhtic and ..

1 mole of an atom = 1 gram atomic weight of an atom 1 mole of a molecule = 1 gram molecular weight of molecule 1 mole of a gas = 22.4 liters of gas at STP 1 mole of a substance = 6.023 x 10 2 3 , atoms, molecules or ions Molecular weight = 2 x Vapor density ..

, (+) - thyroxine, has none of this effect but is used to lower the cholesterol levels. In foods, the chirality of compounds determines the nutritional value, sensory properties or biological activity. Enantiomers of a chemical may have very different flavors. Detection of an unnatural ra..

Introduction - All elements in the periodic table have been classified as metals and non-metals. The non-metals are placed on the right hand side of the periodic table. Non-metals are simple small molecules that are mostly gases. Elements between metals and non-metals are regarded as semi-metals an..

Physical Properties - Hydrogen is a colourless, odourless and tasteless gas. Impure hydrogen has a fishy smell due to its impurities ,arsine and phosphine. Hydrogen is the lightest element. It is by far the most abundant element in the universe and makes up about 90% o..

Hydrogen Fuel - Our present day life highly banks upon the use of fossil fuels such as coal, natural gas, LPG, gasoline, etc. for the production of energy. Our reserves of fossil fuels are getting depleted at an alarming rate and they may get exhausted by the middle of 21 s t ce..

The basic principle involved in the preparation of hydrogen bomb is nuclear fusion. A nuclear fission reaction initiates the fusion reaction. In a hydrogen bomb the set up for fission reaction is surrounded by a mixture of deuterium ( 2 1 H) and lithium. Th..
