Among following compounds, the number of those present in copper matte is ______ .

Options

A. `CuCO_3`
B. `Cu_(2)S`
C. `Cu_(2)O`
D. `FeO`

Answer

To determine the number of compounds present in copper matte, we need to analyze the compounds typically found in copper matte.

### Step-by-Step Solution:

1. **Understanding Copper Matte**:
- Copper matte is a product obtained during the smelting of copper ores. It primarily consists of copper sulfide (Cu₂S) and iron sulfide (FeS).

2. **Identifying the Compounds**:
- The question provides a list of compounds:
- Copper carbonate (CuCO₃)
- Copper sulfide (Cu₂S)
- Copper oxide (CuO)
- Iron oxide (FeO)

3. **Analyzing Each Compound**:
- **Copper Carbonate (CuCO₃)**: This compound is not present in copper matte. It is typically formed from the weathering of copper ores.
- **Copper Sulfide (Cu₂S)**: This is a major component of copper matte. It is formed during the smelting process.
- **Copper Oxide (CuO)**: This compound is not present in copper matte. It can be formed during the oxidation of copper but is not a component of matte.
- **Iron Oxide (FeO)**: This compound is also not present in copper matte. Similar to copper oxide, it can form during the oxidation of iron but is not part of the matte.

4. **Conclusion**:
- From the analysis, the only compound present in copper matte is copper sulfide (Cu₂S). Therefore, the number of compounds from the given list that are present in copper matte is **1**.

### Final Answer:
The number of compounds present in copper matte is **1**.
