What is the chemical make-up of hydrazine? What are some
of its properties?
Hydrazine is to ammonia as hydrogen peroxide is to water. The atomic
formula of hydrazine is N2H4, H2N-NH2. It has a melting point of 2 degrees
Celsius, and a boiling point of 113.5 degrees Celsius. It is fairly toxic,
causing burns by contact in addition to poisoning if ingested or inhaled.
It burns vigorously in air, and if exposed to the atmosphere will react
with carbon dioxide to form the explosive carbazic acid.
