important uses of hydrogen

Uses of Hydrogen - In many electrolysis reactions hydrogen is an important by-product. Enormous quantities of hydrogen are used in the manufacture of ammonia and in the synthesis of methyl alcohol. The hydrogenation of oils to pr..

- The food passively sinks into the body on contact. ..

Liquid hydrogen is used as an important rocket fuel because of its low mass and high enthalpy of combustion. The chemical reaction involved is:..

Some important results - Given a, b, c and d are non-zero real numbers, we can deduce other proportions by simple Algebra. These results are often referred by the names mentioned along each of the properties obtained. (1) If then bc = ad This property is known as INVERTENDO. (2)..

Hydrogen is an important alternative energy source. Some advantages of hydrogen are: Hydrogen is abundantly available in the combined form as water. Use of hydrogen as fuel provides pollution free atmosphere because its combustion pr..

The hydrogenation of oils to produce edible fats, of coal to form synthetic petroleum, and of petroleum oils to enrich the petrol fraction requires large amounts of hydrogen..

(i) Methanoic acid [Formic acid HCOOH] - It occurs in a variety of biting and stingins plants and insects. It is manufactured by the reaction of carbomonoxide with sodium hydroxide under pressure at 473 K. Sodium methanoate is obtained which is acidified and distilled to give the aci..

The measurement of dipole moment helps in distinguishing between polar and non-polar molecules. Non-polar molecules have zero dipole moment while polar molecules have some value of dipole moment. For example: Non-polar molecules: O 2 , Cl 2 , BF 3 , CH 4 Polar Molecules: HF ..

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..
