Answer 1

To determine the bond energy of each carbon-oxygen double bond in carbon dioxide (CO₂), we can analyze the information given in the question.

1. The chemical formula for carbon dioxide (CO₂) indicates that there are 2 carbon-oxygen double bonds in each molecule of CO₂.

2. The total bond energy found in all the bonds of carbon dioxide is given as 1,472 kJ.

Since there are 2 carbon-oxygen double bonds in CO₂, we can calculate the bond energy of each double bond as follows:

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

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

Thus, the correct answer is:

**736 kJ**.
