Chapter 10, Problem 10.79SP

Interpretation Introduction

(a)

Interpretation:

The decomposition reaction of ${\text{PbSO}}_{\text{3}}$ should be balanced.

Concept introduction:

In order to balance the atoms suitable stoichiometric coefficients is placed before the element/elements to ensure equal atoms on both sides. The equation is checked to ensure the number of atoms of each element in accordance with law of mass conservation. The states of matter are specified in parenthesis.

Interpretation Introduction

(b)

Interpretation:

The volume of ${\text{SO}}_{\text{2}}$ gas produced by the reaction of ${\text{250 g PbSO}}_3$ is to be calculated.

Concept introduction:

The combination of all the gas laws namely Boyle’s law, Charles law and Avogadro’s lead to ideal gas equation that relates all the four properties such as given below:

$PV=nRT$

Where,

• $R$ is gas constant.
• $V$ denotes the volume.
• $n$ denotes number of moles.
• $T$ denotes temperature.
• $P$ denotes pressure.
