(a)

Answer to Problem 55QRT
The missing product is
Explanation of Solution
Given nuclear equation in the problem statement is,
In a balanced nuclear equation, the mass number balance and atomic number balance has to be equal on both sides of the equation. The unknown element that is formed is represented as
Sum of mass number in the reactant side has to be equal to the sum of mass number in the product side.
Therefore, the mass number of the unknown product is found to be 140.
Sum of atomic number in the reactant side has to be equal to the sum of atomic number in the product side.
Therefore, the atomic number of the unknown product is found to be 54. The element with atomic number 54 is Xenon. Therefore, the missing product is found to be

Explanation of Solution
Given nuclear equation in the problem statement is,
In a balanced nuclear equation, the mass number balance and atomic number balance has to be equal on both sides of the equation. The unknown element that is formed is represented as
Sum of mass number in the reactant side has to be equal to the sum of mass number in the product side.
Therefore, the mass number of the unknown product is found to be 101.
Sum of atomic number in the reactant side has to be equal to the sum of atomic number in the product side.
Therefore, the atomic number of the unknown product is found to be 41. The element with atomic number 41 is Niobium. Therefore, the missing product is found to be

Answer to Problem 55QRT
The missing product is
Explanation of Solution
Given nuclear equation in the problem statement is,
In a balanced nuclear equation, the mass number balance and atomic number balance has to be equal on both sides of the equation. The unknown element that is formed is represented as
Sum of mass number in the reactant side has to be equal to the sum of mass number in the product side.
Therefore, the mass number of the unknown product is found to be 92.
Sum of atomic number in the reactant side has to be equal to the sum of atomic number in the product side.
Therefore, the atomic number of the unknown product is found to be 36. The element with atomic number 36 is Krypton. Therefore, the missing product is found to be
