Answer:
A. Some of the mass is converted to energy.
B.The products can weigh less than the reactants.
Explanation:
Nuclear reaction: A reaction in which a nuclei splits into two or more smaller nuclei of mass less than the reactants ,or two or more nuclei combined together to form heavy nuclei of mass less than the reactants and huge amount of energy released.
Nuclear reactions are of two types
1. Nuclear fission
2.Nuclear fusion
1. Nuclear fusion: A reaction in which two or more lighter nuclei combined together to form heavy nuclei of mass slightly less than the total mass of reactants and a large amount of energy released. Because the difference in mass of reactants and products change into energy .
2.Nuclear fission: A reaction in which a heavy nuclei splits into two or more lighter nuclei of total mass slightly less than the mass of reactant. Because the difference in mass of product and reactant change into energy therefore, a huge amount of energy released during this reaction.
Therefore, Option A and B are correct.
Answer : A. Some of the mass is converted to energy.
B.The products can weigh less than the reactants.
