Answer:
[tex]PbS_{(s)}+PbSO_4_{(s)}\overset{\Delta}{\rightarrow} 2Pb_{(l)}+2SO_2_{(g)}[/tex]
Explanation:
The balanced reaction of heating solid lead (II) sulfide with the solid lead (II) sulfate to produce liquid lead and sulfur dioxide gas is shown below:
[tex]PbS_{(s)}+PbSO_4_{(s)}\overset{\Delta}{\rightarrow} 2Pb_{(l)}+2SO_2_{(g)}[/tex]
In the balance reaction above, all the phases are indicated. This reaction is used for the production of lead metal.
