Chemistry - Complete P-block Question with Solution | TestHub

The oxides ${\mathrm{SO}}_2$, ${\mathrm{Cl}}_2{\mathrm{O}}_7$, and ${\mathrm{CO}}_2$ are acidic oxides, formed by non-metals. ${\mathrm{Pb}}_3{\mathrm{O}}_4$ is a mixed oxide of lead, specifically a combination of $\mathrm{PbO}$ and ${\mathrm{PbO}}_2$, and is amphoteric. Therefore, ${\mathrm{Pb}}_3{\mathrm{O}}_4$ is different.
