This is clearly a redox reaction:

Dioxygen gas is reduced to oxide anion; sulfide anion is oxidized to sulfur dioxide.

Explanation:

#"Lead sulfide + oxygen gas "rarr" Lead Oxide + sulfur dioxide"#

#PbS(s) + 3/2O_2(g) rarr PbO(s) + SO_2(g)#

Sulfide anion is oxidized to sulfur dioxide; dioxygen gas is reduced to oxide anion. This is formally a 6 electron transfer. Is this balanced? How could I remove the non-integral coefficient?
