Justify that the following reactions are redox reactions :
`CuO(s)+H_(2)(g)toCu(s)+H_(2)O(g)`

Explanation

To justify that the reaction \( \text{CuO(s) + H}_2(g) \rightarrow \text{Cu(s) + H}_2\text{O(g)} \) is a redox reaction, we need to analyze the oxidation states of the elements involved in the reaction and determine if there is a transfer of electrons.

### Step 1: Write the reaction
The given reaction is:
\[ \text{CuO(s) + H}_2(g) \rightarrow \text{Cu(s) + H}_2\text{O(g)} \]

### Step 2: Assign oxidation states
Next, we assign oxidation states to each element in the reaction:
