introduction | there are about 4,000 trillion tons of gas in the atmosphere, of which nitrogen accounts for 78%. it is slightly soluble in water and alcohol, is non-flammable, and is considered a suffocating gas. Although nitrogen is considered an inert element, it forms some very active compounds. It can be used as a diluent and control natural burning and breathing rates, faster at higher oxygen concentrations. It is essential in life, and its compounds can be used as food or fertilizer. |
Use | Nitrogen 15-N2 is an isotope gas of nitrogen, commonly used in nuclear magnetic resonance, biological isotope labeling, protein macromolecular structure research, etc. |
