Is this statement true or false When nuclear reactions happen the total amount of energy changes It is the mass plus energy before and after the reaction that are equal?

That is false. Assuming an exothermic reaction, e.g., a fusion of hydrogen to helium:
- The total amount of mass before and after the reaction is the same. (Any energy leaving the atom has a mass equivalent.)
- The total amount of energy before and after the reaction is the same. (The energy was there previously, in the form of potential energy).

Are nuclear reactions and nuclear fusions the same thing?
Nuclear fusion is a nuclear reaction, but so is fission. So not all nuclear reactions are fission.
How is a nuclear fission reaction controlled in a nuclear reaction?
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
What is controlled nuclear reactions?
A controlled nuclear reaction is one in which the average number of reactions per second does not increase.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
Are radioactive reactions redox reaction?
Radioactive reaction is a red-ox reaction. This is a nuclear decay.
Which statement describes the differences between chemical reactions and nuclear decay rates?
Nuclear decay rates vary, but chemical reaction rates are constant
What is the most important characteristic of a nuclear reaction?
Nuclear reactions involve the reaction of nuclei and does not involve transfer of electron as in regular chemical reactions.
Nuclear reactions change the composition of an atom's?
Nuclear reactions change the composition of an atom's nucleus, hence nuclear reaction.
Are nuclear reactions and nuclear fusions the same thing?
Nuclear fusion is a nuclear reaction, but so is fission. So not all nuclear reactions are fission.
How is a nuclear fission reaction controlled in a nuclear reaction?
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
What is the equation that calculates in nuclear reactions?
What is the equation that calculates in nuclear reaction?
What is controlled nuclear reactions?
A controlled nuclear reaction is one in which the average number of reactions per second does not increase.
Reaction that involves a change in the nucleus?
The general term is "nuclear reaction". An atom may emit alpha, beta, or gamma rays; it may split into two or three smaller parts (fission), or two lighter atoms may combine into a heavier one (fusion).
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
Are radioactive reactions redox reaction?
Radioactive reaction is a red-ox reaction. This is a nuclear decay.
How much more powerful between chemical and nuclear reactions?
A nuclear reaction is much powerful than a chemical reaction.
How is a nuclear fission reaction controlled in a nuclear reactor?
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
