If lead(II) sulfide, $\text{PbS}$, is heated in air, sulfur dioxide and lead(II) oxide are produced. What is the equation for the reaction between $\text{PbS}$ and oxygen?
- A$\text{PbS} + 2\text{O}_2 \rightarrow \text{SO}_2 + \text{PbO}_2$
- B$\text{PbS} + 2\frac{1}{2}\text{O}_2 \rightarrow \text{SO}_3 + \text{PbO}_2$
- C$\text{PbS} + 1\frac{1}{2}\text{O}_2 \rightarrow \text{SO}_2 + \text{PbO}$
- D$\text{PbS} + 2\text{O}_2 \rightarrow \text{SO}_3 + \text{PbO}$
