Chapter 19, Problem 99CP

Interpretation Introduction

Interpretation: The decomposition reaction of lead (IV) halide $\left({\text{PbX}}_{\text{4}}\right)$, mass of ${\text{PbX}}_{\text{4}}$ and ${\text{PbX}}_{\text{2}}$ is given. The halogen $\text{X}$ is to be identified.

Concept introduction: The number of moles is calculated using the formula,

$\text{Number}\text{of}\text{moles}=\frac{\text{Given}\text{mass}}{\text{Molar mass of the compound}}$

Molar mass is the sum of each element of a compound multiplied by the number of atoms present.

To determine: The halogen $\text{X}$ in the decomposition reaction of lead (IV) halide.
