Lead can be extracted from lead(II) sulfide, PbS, in two stages.
Stage 1: Lead(II) sulfide is heated in air. It reacts with oxygen to produce lead(II) oxide and sulfur dioxide.
Stage 2: The Lead(II) oxide is then heated in a blast furnace with coke.
(a) Write a chemical equation for the reaction in Stage 1.

To write the chemical equation for the reaction in Stage 1, we need to identify the reactants and products involved.
Reactants:
1. Lead(II) sulfide (PbS)
2. Oxygen (Oâ‚‚)
Products:
1. Lead(II) oxide (PbO)
2. Sulfur dioxide (SOâ‚‚)
Now, let's write the balanced chemical equation for Stage 1:
PbS + O₂ → PbO + SO₂
Please note that the equation is not yet balanced, so we need to balance it by adjusting the coefficients.
