Answer 2

uses of hydrogen are the following:

• commercial fixation of nitrogen from the air in the Haber ammonia process.
• hydrogenation of fats and oils.
• methanol production, in hydrodealkylation, hydrocracking, and hydrodesulphurization.
• rocket fuel
• welding
• production of hydrochloric acid.
• reduction of metallic ores.
• for filling balloons (hydrogen gas much lighter than air; however it ignites easily).
• liquid H2 is important in cryogenics and in the study of superconductivity since its melting point is only just above absolute zero.
