The chemical makeup of ammonia is NH3, consisting of one nitrogen atom bonded to three hydrogen atoms. This arrangement gives ammonia its distinct properties, making it a colorless gas with a strong, pungent odor. It is commonly produced through the Haber process, where nitrogen from the air and hydrogen derived from fossil fuels are combined under high temperature and pressure to create ammonia. Ammonia is widely used in fertilizers, industrial applications, and cleaning agents due to its effectiveness in breaking down grease and dirt. Additionally, it serves as a building block for synthesizing various nitrogen-containing compounds.
