Hot copper wire reacts with oxygen to produce:

Options

A. `Cu_(2)O`
B. `CuO_(2)`
C. `Cu_(2)O_(2)`
D. `CuO`.

Explanation

To solve the question "Hot copper wire reacts with oxygen to produce," we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are hot copper wire (Cu) and oxygen (O₂).

### Step 2: Write the Reaction
When hot copper wire reacts with oxygen, it undergoes oxidation. The reaction can be represented as:
\[ 2 \text{Cu} + \text{O}_2 \rightarrow 2 \text{CuO} \]
This indicates that two moles of copper react with one mole of oxygen to produce two moles of copper(II) oxide.

### Step 3: Identify the Product
The product formed in this reaction is copper(II) oxide (CuO), which is known to be a black compound.

### Step 4: Analyze the Options
Now, let's analyze the options provided:
1. Cu₂O - This is copper(I) oxide, which is red in color.
2. CuO₂ - This is not a stable compound.
3. Cu₂O₂ - This is also not a stable compound.
4. CuO - This is copper(II) oxide, which is black in color.

### Step 5: Conclusion
The correct answer to the question is that hot copper wire reacts with oxygen to produce copper(II) oxide (CuO), which is black in color.

### Final Answer
Hot copper wire reacts with oxygen to produce copper(II) oxide (CuO).
