Write the chemical formula for each ionic compound below. Lead(II) sulfide is so insoluble that it is almost nontoxic, but pyrolysis of the material, as in smelting, gives dangerous fumes. Pourquoi une telle réglementation ? CuisineAZ a enquêté et nous en dit plus ! The presence of hydrogen sulfide or sulfide ions may be tested using "lead acetate paper.". If this is the case, it would be the first time the substance was identified on a foreign planet. Objects that emit radiation in these wavelengths still have to be quite hot—several hundred degrees Celsius—but not as hot as those detectable by uncooled sensors. Example Reactions: • PbS + 4 H2O2 = PbSO4 ↓ + 4 H2O. Publisher: Cengage Learning. 4 weeks (Dosed-Feed) (C88040) Completed . γ = 90,00 ° The high dielectric constant of PbS leads to relatively slow detectors (compared to silicon, germanium, InSb, or HgCdTe).
