<u>Answer:</u> The energy released in the given nuclear reaction is 1.3106 MeV.
<u>Explanation:</u>
For the given nuclear reaction:

We are given:
Mass of
= 39.963998 u
Mass of
= 39.962591 u
To calculate the mass defect, we use the equation:

Putting values in above equation, we get:

To calculate the energy released, we use the equation:

(Conversion factor:
)

Hence, the energy released in the given nuclear reaction is 1.3106 MeV.
Answer:
D. Photosynthesis uses carbon dioxide while cellular produces carbon dioxide
90% of energy is lost. only 10% is left.
therefore the answer is B. 90%
In exothermic reactions, there is a release heat and the replacement of weak bonds with stronger ones.
