When solid lead(II) sulfide ore burns in oxygen gas, the products are solid lead(II) oxide and sulfur dioxide gas.? Lead sulfide must be stored to avoid contact with oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates) and chemically active metals (such as potassium, sodium, magnesium, and zinc), since violent reactions occur. Sulfide. barium chloride lead (II) oxide iron (III) sulfide phosphorous trihydride calcium bromate sodium oxide potassium permanganate barium persulfate sodium hydrogen carbonate phosphoric acid hydrobromic acid nitrogen trihydride potassium hydroxide chlorous acid copper (II) chloride decahydrate lithium hydride 2. Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O.PbO occurs in two polymorphs: litharge having a tetragonal crystal structure, and massicot having an orthorhombic crystal structure.Modern applications for PbO are mostly in lead-based industrial glass and industrial ceramics, including computer components. 2 PbS + 3 O2 → 2 … Lead sulfide and several other lead compounds are used as detection element material in various infra-red sensors.
