Classify each of the following reactions as combination, decomposition, displacement or double displacement reactions :
`2CuO_((s))to2Cu_((s))+O_(2(g))`

Explanation

To classify the reaction \( 2CuO_{(s)} \rightarrow 2Cu_{(s)} + O_{2(g)} \), we will follow these steps:

### Step 1: Identify the Reactants and Products
In the given reaction, the reactant is \( CuO \) (copper(II) oxide), and the products are \( Cu \) (copper) and \( O_2 \) (oxygen gas).

### Step 2: Determine the Number of Reactants
We note that there is only one reactant (\( CuO \)) on the left side of the equation.
