Comment whether this Reaction is correct? and balance this.

Explanation

To determine if the reaction is correct and to balance it, we will follow these steps:

### Step 1: Write the unbalanced reaction
The given reaction is:
\[ \text{CO} + \text{O}_2 \rightarrow \text{CO}_2 \]

### Step 2: Identify the number of atoms of each element on both sides
- **Reactants:**
- Carbon (C): 1 (from CO)
- Oxygen (O): 2 (1 from CO and 2 from O2, total = 3)

- **Products:**
- Carbon (C): 1 (from CO2)
- Oxygen (O): 2 (from CO2)

### Step 3: Check if the reaction is correct
The reaction is correct because carbon monoxide (CO) reacts with oxygen (O2) to produce carbon dioxide (CO2).

### Step 4: Balance the reaction
To balance the reaction, we need to ensure that the number of atoms of each element is the same on both sides.

1. We have 1 carbon atom on both sides, which is balanced.
2. For oxygen, we have 3 oxygen atoms on the reactant side (1 from CO and 2 from O2) and 2 oxygen atoms on the product side (from CO2).

To balance the oxygen, we can adjust the coefficients:
- Since we need 2 oxygen atoms from O2 to balance with CO2, we can use a coefficient of 1 for CO and 1/2 for O2.

Thus, we can rewrite the balanced equation as:
\[ \text{2 CO} + \text{O}_2 \rightarrow \text{2 CO}_2 \]

### Final Balanced Equation
The balanced reaction is:
\[ 2 \text{CO} + \text{O}_2 \rightarrow 2 \text{CO}_2 \]

### Conclusion
This reaction is correct and balanced.
