• B. $\mathrm{PbO}$
• C. ${\mathrm{pbcl}}^2$
• D. ${\mathrm{PbCl}}_2$

Answer 1

The correct option is B

• A compound is defined as a pure substance that is made up of two or more elements in a fixed ratio by mass.
• The compound formed by the chemical reaction between lead $\left(\mathrm{Pb}\right)$ and oxygen $\left(\mathrm{O}\right)$ is written as $\mathrm{PbO}$. The name of $\mathrm{PbO}$ is Lead oxide.
• It is formed when one atom of lead combines with one atom of oxygen.

Hence, option (B) is the correct answer. The compound formed by the chemical reaction between lead and oxygen is written as $\mathrm{PbO}$.
