Which of the followgin are correctly matched?

Options

A. Turquoise `rarr CuAl_(6)(PO_(4))_(4) (OH)_(8). 4H_(2)O`
B. Peacock ore `rarr Cu_(4)FeS_(2)`
C. Malachite `rarr CuCO_(3). Cu(OH)_(2)`
D. Chacopyrites `rarr CuFeS_(2)`

Explanation

To determine which of the given ores are correctly matched with their formulas, we will analyze each ore and its corresponding chemical formula step by step.

### Step-by-Step Solution:

1. **Understanding Ores**:
- An ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted profitably.

2. **Analyzing Turquoise**:
- Given: Turquoise
- Formula: CuAl6(PO4)4(OH)8·4H2O
- **Analysis**: This formula is indeed correct as turquoise is a phosphate mineral of copper and aluminum.
- **Conclusion**: Turquoise is correctly matched.

3. **Analyzing Peacock Ore**:
- Given: Peacock Ore
- Formula: Cu5FeS4
- **Analysis**: Peacock ore is also known as bornite, but its correct formula is Cu5FeS4. Therefore, this formula is correct.
- **Conclusion**: Peacock Ore is correctly matched.

4. **Analyzing Malachite**:
- Given: Malachite
- Formula: CuCO3·Cu(OH)2
- **Analysis**: This formula is correct as malachite is a carbonate mineral of copper.
- **Conclusion**: Malachite is correctly matched.

5. **Analyzing Chalcopyrite**:
- Given: Chalcopyrite
- Formula: CuFeS2
- **Analysis**: This formula is correct as chalcopyrite is a sulfide mineral of copper and iron.
- **Conclusion**: Chalcopyrite is correctly matched.

### Summary of Findings:
- **Turquoise**: Correctly matched.
- **Peacock Ore**: Correctly matched.
- **Malachite**: Correctly matched.
- **Chalcopyrite**: Correctly matched.

### Final Answer:
The ores that are correctly matched with their formulas are **Turquoise, Peacock Ore, Malachite, and Chalcopyrite**.
