It is also used in cryosurgery. N2 is almost non-reactive at ordinary temperatures. 2. Assuming you mean N2 - nitrogen gas: Physical properties - Boiling point (77.36 K), Molecular weight (roughly 28 g/mol) Chemical properties - Nitrogen is … Gaseous nitrogen is not a reactive compound in room conditions. Nitrogen differs from the other elements of the group in several aspects like: At ordinary temperatures, nitrogen is a gas while all other elements of the group are solids. Sulfur is yellow. It is also used in cryosurgery. By understanding how the nitrogen cycle works people can change their actions and protect the environment. Magnesium and aluminum continue burning in an atmosphere of nitrogen forming their nitrides. Due to this it is inert at room temperature. To identify a chemical property, we look for a chemical … ... Plants can use the nitrogen as either the cation ammonium, NH 4 +, or the anion nitrate, NO 3-. The present name nitrogen is derived from nitre which is a well known nitrogenous compound. It has very low solubility in water (23.2, is almost non-reactive at ordinary temperatures. Ammonia, also called azane or nitrogen trihydride, is the simplest inorganic base and an important source of nitrogen for many applications. This changed the amount of nitrogen found in living organisms and in the air, soil, and water. Calcium, strontium, and barium react with N. in presence of electric arc (above 3273K) to form nitric oxide. In the chemical industry, nitrogen is used as a preventive of oxidation or other deterioration of a product, as an inert diluent of a reactive gas, as a carrier to remove heat or chemicals and as an inhibitor of fire or explosions. Applications. Properties, uses and applications of nitrogen gas and nitrogen liquid. When it returns to the soil from a decaying plant it can be used again by another plant. This leaves three unpaired electrons for bonding and reactions. It is the hardest material known to man and more or less inert - able to withstand … Lavoisier established its elemental nature and named it azote. N2 combines with some highly electropositive metals at high temperatures forming their nitrides. Uses of Nitrogen Gas. Lavoisier established its elemental nature and named it azote. 78% of atmosphere is covered by nitrogen gas.
