Answer: The first step in the industrial recovery of zinc
Chapter 6, Problem 25P(choose chapter or problem)
The first step in the industrial recovery of zinc from the zinc sulfide ore is roasting, that is, the conversion of ZnS to ZnO by heating
\(2 \mathrm{ZnS}(s)+3 \mathrm{O}_{2}(g) \rightarrow 2 \mathrm{ZnO}(s)+2 \mathrm{SO}_{2}(g)\)
\(\Delta H=-879\ \mathrm{kJ}/\mathrm{mol}\)
Calculate the heat evolved (in kJ) per gram of ZnS roasted
