Hydrazine is an inorganic compound with the chemical formula N 2 H 4.It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour.Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (N 2 H 4 ·xH 2 O).
Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. . Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou
Triangular diagrams are not commonplace. The easiest way to understand them is to briefly go through three basic steps in their construction. Consider the first triangular diagram below, which shows all possible mixtures of methane, oxygen and nitrogen. Air is a mixture of about 21 volume percent oxygen, and 79 volume percent inerts (nitrogen ...
Hydrazine nitrate is an inorganic compound with the chemical formula N 2 H 4 ·HNO 3.It has usage in liquid explosives as an oxidizer.It exists in two crystalline forms, stable α-type and unstable β-type.
The attendant wears a full hazmat suit due to the hazards of the hypergolic fuel hydrazine, here being loaded onto the MESSENGER space probe. A hypergolic propellant is a rocket propellant combination used in a rocket engine, whose components spontaneously ignite when they come into contact with each other.
Molecular models may be created for several reasons – as pedagogic tools for students or those unfamiliar with atomistic structures; as objects to generate or test theories (e.g., the structure of DNA); as analogue computers (e.g., for measuring distances and angles in flexible systems); or as aesthetically pleasing objects on the boundary of ...

A traditional route to diimide involves oxidation of hydrazine with hydrogen peroxide or air. [1]N 2 H 4 + H 2 O 2 → N 2 H 2 + 2H 2 O. Alternatively the hydrolysis of diethyl azodicarboxylate or azodicarbonamide affords diimide: [2]
