Unfortunately, there is no existence of the chemical compound N2H26. In this formula, you have 2 Nitrogen (N) atoms and 26 Hydrogen (H) atoms, however, in reality, Nitrogen atoms cannot bond with so many Hydrogen atoms.
You might be thinking of ammonia (NH3), a very important chemical compound that consists of 1 Nitrogen atom and 3 Hydrogen atoms. Ammonia is a colorless gas with a distinct smell. It can react with metals, acids, and salts, and can be synthesized both in the laboratory and industrially.
Or you might be thinking of hydrazine (N2H4), a chemical compound that consists of 2 Nitrogen atoms and 4 Hydrogen atoms. Hydrazine is a colorless liquid, has strong reducing properties, and is often used as a reactant in aerospace technology and pharmaceutical chemistry.
