The element obtained primarily from the distillation of liquid air is nitrogen (N). To understand why, let's first discuss what liquid air is and how it is obtained.
Liquid air is a liquid form of air that is produced by cooling and compressing ordinary air. It is created through a process called air liquefaction, which involves cooling the air until it becomes a liquid. This process typically involves a series of steps that include compression, cooling, and distillation.
During distillation, the liquid air is heated and allowed to evaporate. Each component in the air, including nitrogen (N), oxygen (O), argon (Ar), carbon dioxide (CO2), and other trace gases, has a different boiling point. As a result, when the liquid air evaporates, the different gases can be separated based on their boiling points.
Since nitrogen (N) has a boiling point of -195.8°C (-320.4°F), it is one of the major components of liquid air and is obtained primarily from the distillation process. It is worth noting that argon (Ar) is also obtained from the distillation of liquid air, as it has a lower boiling point (-185.9°C or -302.6°F) than nitrogen.
Therefore, the correct answer to the question "Which element is obtained primarily from the distillation of liquid air?" is nitrogen (N).
