Which of the following statement is incorrect

Options

A. Silver glance mainly contains silver sulphide
B. Gold is found in native state
C. Zinc blende mainly contain zinc chloride
D. Copper pyrites also contains `Fe_(2)S_(3)`

Answer

To determine which statement is incorrect, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Analyze Option A**:
- The statement claims that "Silver glands mainly contain silver sulphide."
- Silver sulphide is represented by the chemical formula Ag2S.
- This statement is correct as silver glands (or ores) do contain silver sulphide.

**Hint**: Check the chemical composition of silver ores to verify the statement.

2. **Analyze Option B**:
- The statement claims that "Gold is found in native state."
- Gold is known for its low reactivity and is often found in its native form, which is elemental gold (Au).
- This statement is correct since gold does not readily react with other elements.

**Hint**: Consider the reactivity series of metals to understand why gold is found in its native state.

3. **Analyze Option C**:
- The statement claims that "Zinc blend mainly contains zinc chloride."
- Zinc blend is actually zinc sulfide (ZnS), not zinc chloride (ZnCl2).
- This statement is incorrect because it misidentifies the main component of zinc blend.

**Hint**: Look up the chemical formula of zinc blend to confirm its composition.

4. **Analyze Option D**:
- The statement claims that "Copper pyrite also contains Fe2H2."
- Copper pyrite, also known as chalcopyrite, has the formula CuFeS2.
- While it does contain iron (Fe), the formula Fe2H2 is incorrect. Copper pyrite does not contain this specific compound.
- This statement is also incorrect.

**Hint**: Review the composition of copper pyrite to clarify its constituents.

### Conclusion:
Based on the analysis, the incorrect statements are found in Option C ("Zinc blend mainly contains zinc chloride") and Option D ("Copper pyrite also contains Fe2H2"). However, since the question asks for which statement is incorrect, we can conclude that Option C is the most straightforwardly incorrect statement regarding the main component of zinc blend.

### Final Answer:
**Option C is incorrect.**
