Question

The toxic vapour of which of the following
substances are present in damaged
fluorescent tubes and CFL's?
a. Chlorine
b. Mercury
C. Carbon monoxide
d. Ozone​

Answer 1

Answer:

B option Mercury

Explanation:

Using CFLs (and other fluorescent bulbs) instead of incandescent bulbs reduces the amount of mercury released into the environment. Mercury is found in many rocks, including coal.

Answer 2

The toxic vapour of (b) Mercury substances are present in damaged

fluorescent tubes and CFL's

Explanation:

The toxic vapour:

Fluorescent lighting manufacturers are attempting to lower the quantity of mercury in CFLs. When the bulbs are in good condition, no mercury is discharged (i.e., not broken)

• Chlorine:Chlorine is a chemical element with the atomic number 17 and the symbol $cl$ It is the second-lightest of the halogens, appearing in the periodic table between fluorine and bromine, and its characteristics are generally halfway between them. At room temperature, chlorine is a yellow-green gas.
• Mercury:Mercury is sometimes known as "quicksilver" or "liquid silver." Mercury is known as a "Transition Metal" because of its ductility, and ability to conduct heat and electricity.
• Carbon monoxide: Carbon monoxide is a combustible gas that is colourless, odourless, and tasteless. It is somewhat less dense than air. One carbon atom and one oxygen atom make up carbon monoxide. It is the oxocarbon family's most basic chemical.
• Ozone​: The inorganic molecule ozone, often known as trioxygen, has the chemical formula $O3$. It's a pale blue gas with a pronounced unpleasant odour. It is a far less stable allotrope of oxygen than the diatomic allotrope $O2$, breaking down to $O2$ in the lower atmosphere.
