2 answers:
Answer: Option (A) is the correct answer.
Explanation:
Nuclear chain reactions occur in fission reactions only. Nuclear fission reactions are defined as the reactions in which larger nuclide splits into two or more smaller daughter nuclides.
For example,
These neutrons released will again bombard with the uranium atom leading to another fission reaction and this chain continues. And, if this chain gets disturbed by any external source then reaction becomes out of control as very high amount of energy releases in nuclear reactions.
Hence, in nuclear chain reactions the neutrons which are released in the previous fission reaction act as the starting material in the next reaction. Thus, this process continues to many reactions and hence, is known as nuclear chain reaction.
Thus, we can conclude that fission reactions can get out of control without chain reaction taking place.

Solution :
From the balanced chemical equation, we can say that 1 moles of KBr will produce 1 moles of KCl .
Moles of KBr in 102 g of potassium bromide.
n = 102/119.002
n = 0.86 mole.
So, number of miles of KCl produced are also 0.86 mole.
Mass of KCl produced :
Hence, this is the required solution.
