How many moles of ` CO _ 2 ` is produced when one mole of benzene undergoes combustion ?

Explanation

To determine how many moles of carbon dioxide (CO₂) are produced when one mole of benzene (C₆H₆) undergoes combustion, we can follow these steps:

### Step 1: Write the combustion reaction of benzene.
The combustion of benzene can be represented by the following chemical equation:
\[ \text{C}_6\text{H}_6 + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} \]

### Step 2: Balance the chemical equation.
To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.
