The video tutorial explains the preparation, properties, reactivity, and uses of dinitrogen. Commercially, dinitrogen is produced by fractional distillation of liquefied air. In laboratories, it can be prepared using ammonium chloride and sodium nitride or by thermal decomposition of compounds like barium azide. Dinitrogen is colorless, odorless, and inert at room temperature but becomes reactive at higher temperatures. It forms ionic and covalent nitrides with metals and non-metals, respectively. Dinitrogen is crucial in the production of ammonia and other industrial chemicals, and it is used as a refrigerant and in creating inert atmospheres.
