Question

Quizplus · Accepted Answer

The roasting of PbS involves heating it with oxygen to form PbO and SO2, as shown in the equation 2 PbS(s) + 3 O2(g) -> 2 PbO(s) + 2 SO2(g). Option B is the closest to this equation, with the correct number of reactants and products. The other options either have incorrect stoichiometric coefficients or include unnecessary compounds like S.
