Answer 1

Nitrogen is used in the manufacture of ammonia by the Haber process.

Haber process - The process of production of ammonia from nitrogen and hydrogen in presence of an iron catalyst is called the Haber process.

$\mathrm{Nitrogen}\left(\mathrm{g}\right)+\mathrm{Hydrogen}\left(\mathrm{g}\right)\stackrel{\mathrm{iron}\mathrm{catalyst}}{\to }\mathrm{Ammonia}\left(\mathrm{g}\right)$

Therefore, nitrogen is used in the manufacture of ammonia by the Haber process.
