`KO_2 + CO_2 to `

Options

A. `H_2 `
B. `N_2`
C. `O_2`
D. `CO`

Explanation

To solve the reaction between KO2 (potassium superoxide) and CO2 (carbon dioxide), we can follow these steps:

### Step 1: Identify the Reactants
We have two reactants: KO2 (potassium superoxide) and CO2 (carbon dioxide).

### Step 2: Write the Reaction
When KO2 reacts with CO2, it undergoes a chemical reaction. The balanced equation for this reaction is:

\[ 4 KO_2 + 2 CO_2 \rightarrow 4 K_2CO_3 + 3 O_2 \]

This indicates that potassium superoxide reacts with carbon dioxide to produce potassium carbonate (K2CO3) and oxygen gas (O2).

### Step 3: Identify the Products
From the balanced equation, we can see that the products of the reaction are:
- Potassium carbonate (K2CO3)
- Oxygen gas (O2)

### Step 4: Determine the Correct Option
Among the options provided:
1. H2
2. N2
3. O2
4. CO

Since we produced O2 gas in the reaction, the correct answer is option 3: O2.

### Final Answer
The reaction of KO2 with CO2 produces K2CO3 and O2 gas.
