vekshin1
The answer is <span>b.reaction b releases more energy than reaction a releases.

The reaction a is an example of a chemical reaction while the reaction b is an example of a nuclear reaction. 
</span><span>Some main differences between the chemical and nuclear reactions are:
- The nuclear reaction releases more energy per gram.
- The nuclear reaction takes place in the nucleus of the atom, while in chemical reactions include electrons.
- In the nuclear reaction, part of the mass is converted into energy, which </span><span>violates the law of conservation of mass.
</span>
Therefore, the nuclear reaction (reaction b) will release more energy than the chemical reaction (reaction a).
