What are the products formed when `H_(2)` reacts with CuO?

Options

A. `CuO_(2)+H_(2)`
B. `CuH+H_(2)O`
C. `Cu+H_(2)O`
D. `CuH_(2)+OH`

Answer

To determine the products formed when hydrogen gas (H₂) reacts with copper oxide (CuO), we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are hydrogen gas (H₂) and copper(II) oxide (CuO).

### Step 2: Understand the Reaction Type
This reaction is a redox reaction, which involves both oxidation and reduction processes. In this case:
- Hydrogen (H₂) acts as a reducing agent.
- Copper oxide (CuO) acts as an oxidizing agent.

### Step 3: Determine the Oxidation and Reduction
- **Oxidation**: In this reaction, hydrogen (H₂) is oxidized to water (H₂O). This involves the addition of oxygen.
- **Reduction**: Copper oxide (CuO) is reduced to copper (Cu). This involves the removal of oxygen.

### Step 4: Write the Balanced Chemical Equation
The balanced chemical equation for the reaction is:
\[ \text{H}_2 + \text{CuO} \rightarrow \text{Cu} + \text{H}_2\text{O} \]

### Step 5: Identify the Products
From the balanced equation, we can see that the products formed are:
1. Copper (Cu)
2. Water (H₂O)

### Final Answer
The products formed when H₂ reacts with CuO are copper (Cu) and water (H₂O).
