What is a characteristic of carbon monoxide?

Carbon monoxide is characterized as being colorless and odorless, which makes it particularly hazardous because it can be difficult for individuals to recognize its presence in the environment. This lack of color and odor means that carbon monoxide cannot be detected by human senses, leading to a higher risk of accidental exposure and poisoning, especially in enclosed or poorly ventilated spaces.

Understanding these properties emphasizes the importance of using carbon monoxide detectors in homes and workplaces to alert individuals to its presence, given its dangerous effects on health, including headaches, dizziness, confusion, and even death in high concentrations. The correct choice highlights a critical aspect of safety regarding carbon monoxide, underscoring the need for awareness and monitoring in environments where its presence could be a concern.
