Nitrogen peroxide definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation. Hydrogen peroxide is best known for its medical uses but also has many uses in the garden. rates than the fabric. and remains in equilibrium in a mixture' Nitric acid is prepared in large scale from nitrogen per oxide. Hydrogen peroxide is a covalent peroxide compound having the molecular formula H 2 O 2. Nitrogen Oxides (NOx) Your question should be a bit more specific to give any single chemical formula. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. These two are different molecules having same emperical formula. Hydrogen peroxide is an organic, naturally occurring chemical. N2O4 +H2O =HNO2 +HNO3 Nitrogen tetroxide (formula N2O4; also called dinitrogen tetroxide) actually is a dimer (a molecule formed from two similar constituents called monomers) that dissociates into two molecules of nitrogen dioxide (formula NO2). Nitrogen per oxide or di nitrogen tetra oxide has molecular formula= N2O4 and t remains separated in a mixture with nitrogen dioxide,NO2. The two oxygen atoms are bonded to each other. Dinitrogen tetroxide, commonly referred to as nitrogen tetroxide, and sometimes, usually among ex-USSR/Russia rocket engineers, as amyl, is the chemical compound N 2 O 4.It is a useful reagent in chemical synthesis. It forms an equilibrium mixture with nitrogen dioxide. It consists of two hydrogen molecules and two oxygen molecules (H2O2). It is a covalent compound because all bonds between the four atoms are covalent bonds. The molar mass of hydrogen peroxide is about 34.014 g/mol.
