Which statement correctly describes the characteristics of Nitrous Oxide (N₂O)?

The correct statement about Nitrous Oxide (N₂O) is that it is colorless and has a sweet smell, along with a slightly sweet taste. This distinctive characteristic is important in medical settings, particularly in dentistry and anesthesia, where nitrous oxide is commonly used for its anesthetic and analgesic properties. The sweet-smelling nature of the gas can help patients identify the substance being used, helping to reduce anxiety associated with unknown gases.

Other options inaccurately describe the properties of nitrous oxide. For example, some suggest it has a bitter taste or an odor, which are not characteristics of N₂O. Understanding these properties is crucial for healthcare professionals to ensure safe and effective use of this medical gas.
