Answer:
b.Small
Explanation:
We have to fill in the blanks.
Fusion : It is a process in which heavy nuclei split into lighter nuclei of mass slightly less than the mass of reactant.Because change in mass from reactant to product convert into energy released during nuclear reaction.Therefore, mass of products slightly smaller than the mass of reactants.
Fission:It is a process in which lighter nuclei combined together and formed heavy nuclei of mass slightly less than the mass of reactants because small amount of mass converted into energy released during the reaction.Therefore, the mass of combined together lighter nuclei in reactant is greater than the mass of heavy nuclei in product.
During the process of both fission and fusion nuclear reactions , a large amount of energy released from small amounts of matter.
Answer:b.Small
