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).

Nitric oxide is a nitrogen oxide which is a free radical, each molecule of which consists of one nitrogen and one oxygen atom. It has a role as a neurotransmitter, a signalling molecule, a vasodilator agent, a bronchodilator agent, a radical scavenger, a human metabolite, an Escherichia coli metabolite and a mouse metabolite.

Nitric oxide also known as nitrogen monoxide is a chemical compound. It contains nitrogen in its +2 oxidation state. It contains nitrogen and oxide ions. Its chemical formula is often given as ·N=O.

2025年1月11日 · nitric oxide (NO), colourless toxic gas that is formed by the oxidation of nitrogen. Nitric oxide performs important chemical signaling functions in humans and other animals and has various applications in medicine .

2023年5月3日 · Nitric oxide (NO) is formed by the high temperature oxidation of nitrogen, (8.4.2), or the platinum catalyzed oxidation of ammonia at 800 °C, (8.4.3). N2 + O2 ⇌ 2NO. 4NH3 + 5O2 Pt → 4NO + 6H2O.

2025年1月28日 · Nitric Oxide is represented by its chemical formula NO, is a fascinating molecular compound that plays a crucial role in the world of chemistry and beyond. This colorless gas is made up of nitrogen and oxygen , two elements that are essential for life.

2023年1月25日 · Nitric oxide has the chemical formula NO. It occurs in a gaseous state and is a very reactive molecule. It is an important free radical that participates in various chemical reactions in the atmosphere and in the human body.

By formula: Ni ++NO = (Ni +•NO)

2023年1月16日 · Nitrogen Monoxide (Nitric Oxide) Nitric oxide is a colourless paramagnetic gas. It is made, for example, by the reduction of concentrated nitric acid by copper, or reduction of nitrates and nitrites: HNO 3 + 3Cu 3Cu(NO 3) 2 + 4H 2 O + 2NO; Its reaction include: Oxidation to NO 2 by oxygen or to nitric acid by permanganate (used for its analysis).

The chemical compound nitric oxide is a gas with formula N O. It is an important signaling molecule in the body of mammals, including humans —one of the few gaseous signaling molecules known. It is also a toxic air pollutant produced by automobile engines and power plants.
