Answer 1

To find the bond energy of each carbon-oxygen double bond in carbon dioxide (CO₂), we first need to understand the structure of CO₂. Each carbon dioxide molecule has one carbon atom that is double bonded to two oxygen atoms. This means there are two carbon-oxygen double bonds in each molecule of carbon dioxide.

Given that the total bond energy of all the bonds in one molecule of carbon dioxide is 1,472 kJ, we can find the bond energy of each individual carbon-oxygen double bond by dividing the total bond energy by the number of double bonds:

\[
\text{Bond energy of each C=O bond} = \frac{\text{Total bond energy}}{\text{Number of C=O bonds}} = \frac{1,472 \, \text{kJ}}{2} = 736 \, \text{kJ}
\]

Therefore, the bond energy of each carbon-oxygen double bond in carbon dioxide is **736 kJ**.

So, the correct answer is **736 kJ**.
