The correct Answer is:
To determine the total number of black-colored sulfides among the given compounds, we will analyze each sulfide one by one based on their color characteristics. 1. **Identify the Sulfides:** - PbS (Lead(II) sulfide) - CuS (Copper(II) sulfide) - HgS (Mercury(II) sulfide) - MnS (Manganese(II) sulfide) - Ag2S (Silver sulfide) - NiS (Nickel(II) sulfide) - CoS (Cobalt(II) sulfide) - Bi2S3 (Bismuth(III) sulfide) - SnS2 (Tin(IV) sulfide) 2. **Determine the Color of Each Sulfide:** - **PbS:** Black - **CuS:** Black - **HgS:** Black - **MnS:** Dirty pink (not black) - **Ag2S:** Black - **NiS:** Black - **CoS:** Black - **Bi2S3:** Brownish-black (not considered purely black) - **SnS2:** Yellow (not black) 3. **Count the Black Sulfides:** - From the analysis: - PbS: Black - CuS: Black - HgS: Black - Ag2S: Black - NiS: Black - CoS: Black - Total black sulfides = 6 (PbS, CuS, HgS, Ag2S, NiS, CoS) 4. **Conclusion:** - The total number of black-colored sulfides among the given compounds is **6**.
