Just be aware to look out for decomposition every time you see heating. Nonetheless this is a combustion. So the products should be obvious: ZnO (oxide, right?) and - the only other non-elemental neutral form of S (it's got to be neutral to keep the charge balance across the equation) - SO2.
In general, if you could answer the question of "what products will there be" comprehensively then chemists would have to shut up shop (or department) that very day, because it is around this question that all of that which is properly classified as chemistry is based. (Materials science if you ask me is more physics than chemistry, except when it comes to, once again, reactions.)
