Question

7. State any two uses of hydrogen.​

Answer 1

Answer:

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
