Name one star from the diagram that is not performing nuclear fusion at all. Please give an explanation for your answer as well. I will give a brainiest!

12 number of moles of carbon dioxide are used.

Explanation:

Given data:

Number of moles of oxygen produced = 12 mol

Number of moles of CO₂ used = ?

Solution:

Chemical equation:

6CO₂ + 6H₂O      →     C₆H₁₂O₆ + 6O₂

Now we will compare the moles of oxygen with carbon dioxide.

                     O₂            :          CO₂

                      6             :             6

                    12              :             12

Thus, 12 number of moles of carbon dioxide are used.
