Hey guys I’m struggling, the reaction given is 2CO+O2–>2CO2

It says current monoxide and oxygen combine to produce carbon dioxide. The total bond energy of the products is 1472kJ. The bond energy of each carbon oxygen bond in carbon dioxide it is____.

Is it
368kJ
2,944kJ
736kJ
Or
1,472kJ
Can someone also please explain how to do this thank you!

368 kJ

(Your welcome) :)

736

To determine the bond energy of each carbon-oxygen bond in carbon dioxide, we can use the concept of bond energy and the given information.

First, we need to calculate the total bond energy of the reactants. The reaction equation states that 2 moles of carbon monoxide (CO) and 1 mole of oxygen (O2) are involved. We can find the bond energy of each molecule by checking a table of bond energies.

According to the given reaction, we start with 2CO molecules, which means we need to multiply the bond energy of the CO molecule by 2. Let's assume the bond energy of a CO molecule is X kJ/mol. Therefore, the total bond energy of the carbon monoxide molecules would be 2X kJ/mol.

For oxygen, we have 1 mole of O2. Let's assume the bond energy of an O2 molecule is Y kJ/mol. So, the total bond energy of the oxygen molecules would be Y kJ/mol.

Now, based on the provided information, the total bond energy of the products (carbon dioxide) is given as 1472 kJ/mol. Since there are two carbon-oxygen bonds in one carbon dioxide molecule (CO2), the bond energy of each carbon-oxygen bond can be calculated by dividing the total bond energy of the products by the number of carbon-oxygen bonds.

So, the bond energy of each carbon-oxygen bond in carbon dioxide is:

Total bond energy of the products (1472 kJ/mol) / Number of carbon-oxygen bonds (2)

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

So, the correct answer is 736 kJ.

To find the bond energy of each carbon-oxygen bond in carbon dioxide, you can use the concept of bond enthalpy or bond energy. Bond enthalpy is the energy required to break one mole of a specific bond in a compound.

First, let's look at the balanced chemical equation:
2CO + O2 → 2CO2

From this equation, we can see that two moles of carbon monoxide (CO) react with one mole of oxygen (O2) to form two moles of carbon dioxide (CO2).

Given that the total bond energy of the products is 1472 kJ, and we want to find the bond energy of each carbon-oxygen bond (in CO2), we can divide the total bond energy by the number of carbon-oxygen bonds present in carbon dioxide.

Each carbon dioxide molecule (CO2) contains two carbon-oxygen bonds. Therefore, the bond energy of each carbon-oxygen bond is:

Bond energy of each carbon-oxygen bond = Total bond energy / Number of carbon-oxygen bonds
Bond energy of each carbon-oxygen bond = 1472 kJ / 2
Bond energy of each carbon-oxygen bond = 736 kJ

So the correct answer is 736 kJ.

To recap, you can find the bond energy of each carbon-oxygen bond in carbon dioxide by dividing the total bond energy of the products by the number of carbon-oxygen bonds present in carbon dioxide. In this case, the answer is 736 kJ.
