chemical equation please thanks.


a. In the first step of refining zinc metal from its zinc sulfide ore, the ore is heated in the presence of oxygen. The products are solid zinc oxide and sulfur dioxide gas.

b. The next step of refining zinc involves heating the zinc oxide in the presece of carbon. This reaction produces zinc vapor and carbon monoxide gas.

(a) solid zinc sulfide + oxygen gas -----> solid zinc oxide + sulfur dioxide gas
ZnS(s) + O2(g) ------> ZnO(s) + SO2(g)
2ZnS(s) + 3O2(g) ------> 2ZnO(s) + 2SO2(g)

(b) solid zinc oxide + solid carbon -----> zinc vapor + carbon monoxide gas
ZnO(s) + C(s) -------> Zn(g) + CO(g)
The skeleton equation is the balanced equation.
