Regrettably, the formula N2H18 you provided does not correspond to any known chemical substances. In chemistry, the precise molecular formula is very important, as it indicates the quantity and type of atoms that make up a molecule.
In this case, it seems like you are trying to refer to hydrazine (N2H4), a chemical compound of nitrogen and hydrogen. Hydrazine is a colorless liquid, with a smell similar to ammonia. Hydrazine is widely used in industry as a reducing agent or a reactant in the production of dyes, pesticides, explosives, and antifreeze.
In a laboratory setting, hydrazine can be synthesized from ammonia and chloramine. During industrial production, hydrazine is usually produced from ammonia and organic hydrocarbons.
Hydrazine can react with a variety of other substances such as metals, non-metals, acids, and salts, leading to a range of chemical reactions.
Please review the molecular formula you want to grasp information about and provide accurate information to receive the best information.
