Nitrogen reacts with hydrogen to form which compound?

Nitrogen reacts with hydrogen to form ammonia, which is a compound with the formula NH3. This reaction occurs under specific conditions, typically involving high temperatures and pressures, and often in the presence of a catalyst. The combination of nitrogen and hydrogen is fundamental to the industrial synthesis of ammonia, known as the Haber-Bosch process. Ammonia is a crucial substance used in fertilizers, cleaning agents, and various chemical processes.

The other options listed represent different compounds that do not result directly from the reaction between nitrogen and hydrogen. Hydrogen peroxide consists of hydrogen and oxygen, urea is produced from ammonia and carbon dioxide, and methanol is derived from carbon monoxide and hydrogen. Thus, ammonia is distinctly formed from the direct combination of nitrogen and hydrogen, solidifying its position as the correct answer.
