Answer 2

USES OF HYDROGEN

• 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
