Which one of the following is a property of chlorine gas?

Explanation:
Chlorine gas has a density greater than that of air, so it tends to stay low and accumulate in low-lying areas or near the floor. This comes from its molecular weight—chlorine (Cl2) is about 71 g/mol, while air averages around 29 g/mol. Because it is heavier, leaks can pool in basements, pits, or around barriers, making floor-level detection and ventilation crucial for safety. Chlorine is not harmless to humans; it is a toxic irritant that can injure the eyes, skin, and respiratory system, especially at higher concentrations. It is also not flammable; chlorine itself does not burn, though it is a strong oxidizer and can react violently with certain substances.
