When powdered zinc is heated with sulfur, a violent reaction occurs, and zinc sulfide forms:
Zn(s) + S₈(s) → ZnS(s)
[unbalanced]
Some of the reactants also combine with oxygen in air to form zinc oxide and sulfur dioxide. When 83.2 g of Zn reacts with 52.4 g of S₈, 104.4 g of ZnS forms. (a) What is the percent yield of ZnS?

When the mixture is touched with a heated metal rod, however, a violent reaction occurs (the reaction is termed exothermic; producing heat) and zinc sulfide is formed as the product.

How do you separate zinc and sulfur?

As stated above, it is possible for elemental sulfur in DLR to be separated and purified by distillation methods. Distillation processes not only can recover sulfur from DLR but can con- centrate zinc in the distillation concentrate (DC), which can be used as raw material for zinc metal production.
