To find the bond energy of each carbon-oxygen double bond in carbon dioxide (CO₂), we first need to understand the structure of CO₂. Carbon dioxide has two carbon-oxygen double bonds.

Since the total bond energy for all the bonds in one molecule of CO₂ is given as 1,472 kJ, and there are 2 double bonds, we can determine the bond energy of each bond by dividing the total bond energy by the number of bonds:

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

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