What would this chemical equation be

When lead(II) sulfide is heated to high temperatures in a stream of pure oxygen gas, solid lead(II) oxide forms with the release of gaseous sulfur dioxide. Write the unbalanced chemical equation for this reaction. (Omit states-of-matter in your answer.)

Would it be PbS + O_2 +SO_2 --> PbS??

Close

PbS + O2 -----------> PbO + SO2
