Answer 2

Answer:

$O_{3}$ and $NO_{2}$ are pollutants that contain three atoms. Option b) is correct.

Explanation:

• In a compound, the atoms of the elements are bonded together in a fixed proposition.
• The atoms are bonded together by single, double, or triple bonds.

The pollutant $C_{6} H_{6}$ has six hydrogen atoms and six carbon atoms. So, there are twelve atoms. In the pollutant $NO$, there is a nitrogen atom and an oxygen atom. So, there are two atoms.

In the pollutant, $O_{3}$ there are three oxygen atoms. In the pollutant $NO_{2}$, there are two oxygen atoms and a nitrogen atom. So, there are three atoms.

Hence, $O_{3}$ and $NO_{2}$ are pollutants that contain three atoms.

Option b) is correct.
