Answer 1

Answer:

Uses of Hydrogen

Hydrogen finds a variety of application due to its dual nature. Following are some important uses of hydrogen:

1) Hydrogen is used in the synthesis of ammonia and the manufacture of nitrogenous fertilizers.

2) Hydrogenation of unsaturated vegetable oils for manufacturing vanaspati fat.

3) It is used in the manufacture of many organic compounds, for example, methanol.

4) Hydrogen chloride is a very useful chemical and is prepared from hydrogen.

5) Hydrogen can reduce many metal oxides to metals by metallurgical processes.

6) Hydrogen is used as rocket fuel in many space research activities.

7) Hydrogen fuel is being experimented within the automotive industry with hydrogen fuel cells.

Answer 2

Answer:

Hydrogen also has many other uses. In the chemical industry it is used to make ammonia for agricultural fertiliser (the Haber process) and cyclohexane and methanol, which are intermediates in the production of plastics and pharmaceuticals. It is also used to remove sulfur from fuels during the oil-refining process.
