Standard Enthalpy of Formation of NO2 - CHEMISTRY COMMUNITY
Webb378 rader · Enthalpy is a state function, defined by the internal energy (E), the pressure … Nitrogen dioxide is a chemical compound with the formula NO 2. It is one of several nitrogen oxides. NO 2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year for use primarily in the production of fertilizers. At higher temperatures it is a reddish-brown gas. It can be fatal if inhaled in large quantities. Nitrogen dioxide is a paramagnetic, bent molecule with C2v point group symmetry. platinum cleaning
