Explanation:

1 used in weather balloons

2 hydrogen is used to manufacture ammonia gas through the hai bahut process

3 hydrogen is used to convert vegetable oil into a solid form called vanaspati ji in the present of Nicholas catalyst through the process of hydrogenation

4 hydrogen act as a reducing agent in used to extract metal by reducting their oxides

5 the mixture of hydrogen and oxygen can produce temperature upto 2800 degree Celsius and combination combustion and this mixture is used for welding and cutting the metals

6 the mixture of liquid hydrogen and oxygen is used as a rocket propellants for rocket and other space cycle

this is your answer

Answer 2

Answer :

Uses of hydrogen :-

(i) It is used in making margarine: Margarines are made from vegetable oils. By reacting hydrogen with the natural oil molecules makes the oil thicker.

(ii) Hydrogen is used as a fuel: Hydrogen reacts explosively with the oxygen. So, liquid hydrogen is used as rocket fuel and to power up fuel cells. Reaction is as follows :-

• $\rm{2H_{2(g)}+O_{2(g)}\xrightarrow{\text{Catalyst}}2H_2O_{(g)}}$

(iii) It is used in the manufacture of ammonia for fertilisers.

(iv) Hydrogen directly combines with chlorine to form hydrochloric acid (HCl). Reaction is as follows :-

• $\rm{H_{2(g)}+Cl_{2(g)}\longrightarrow{}2HCl_{(g)}}$

Hydrochloric acid is used for cleaning steel, ammonium chloride medicines and cosmetics.

Some other common uses :-

• Hydrogen is used in the reduction process of metallic ores.
• It is used in the process of welding.
• Hydrogen is also essential in the production of methanol.
