The first step in producing pure lead from galena (PbS)(PbS)(PbS) is as follows: 2PbS(s)+3O2(g)⟶2PbO(s)+2SO2(g) 2{PbS}(s) + 3{O}_2(g) \longrightarrow 2{PbO}(s) + 2{SO}_2(g) 2PbS(s)+3O2(g)⟶2PbO(s)+2SO2(g). All of the following are true concerning this reaction except:
In the redox reaction MnO4−+C2O42−→Mn2++CO2+H2O \text{MnO}_4^- + \text{C}_2\text{O}_4^{2-} \to \text{Mn}^{2+} + \text{CO}_2 + \text{H}_2\text{O} MnO4−+C2O42−→Mn2++CO2+H2O The correct coefficients of C2O42− \text{C}_2\text{O}_4^{2-} C2O42− and H+ \text{H}^+ H+ are
