Nitric oxide (nitrogen oxide or nitrogen monoxide[ 1 ]) is a colorless gas with the formula NO. It is one of the principal oxides of nitrogen. Nitric oxide is a free radical: it has an unpaired electron, which is sometimes denoted by a dot in its chemical formula (• N=O or • NO).
Properties. [edit] Nitrogen dioxide is a reddish-brown gas with a pungent, acrid odor above 21.2 °C (70.2 °F; 294.3 K) and becomes a yellowish-brown liquid below 21.2 °C (70.2 °F; 294.3 K). It forms an equilibrium with its dimer, dinitrogen tetroxide (N2O4), and converts almost entirely to N2O4 below −11.2 °C (11.8 °F; 261.9 K).
Nobelium is a synthetic chemical element; it has symbol No and atomic number 102. It is named after Alfred Nobel, the inventor of dynamite and benefactor of science. A radioactive metal, it is the tenth transuranium element, the second transfermium, and is the penultimate member of the actinide series. Like all elements with atomic number over ...
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
In atmospheric chemistry: NO x (or NOx) refers to the sum of NO and NO 2. [1] [2] NO y (or NOy) refers to the sum of NO x and all oxidized atmospheric odd-nitrogen species (e.g. the sum of NO x, HNO 3, HNO 2, etc.) NO z (or NOz) = NO y − NO x; Mixed Oxides of Nitrogen ("MON"): solutions of nitric oxide in dinitrogen tetroxide/nitrogen dioxide.
In atmospheric chemistry, NOxis shorthand for nitric oxide(NO) and nitrogen dioxide(NO2), the nitrogen oxidesthat are most relevant for air pollution. [1][2]These gases contribute to the formation of smogand acid rain, as well as affecting tropospheric ozone. NOxgases are usually produced from the reaction between nitrogenand oxygenduring ...
Sodium nitrate is the chemical compound with the formula Na N O. 3. This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4][5] to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter.
Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate[9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3−). Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder.
