Is the following nuclear reaction balanced?
a.) yes
b.) no

Answer : Yes, the following nuclear reaction are balanced.

Explanation :

Beta emission or beta minus decay : It is a type of decay process, in which a neutrons gets converted to proton, an electron and anti-neutrino. In this the atomic mass number remains same.

The beta minus decay equation is represented as,

(A is the atomic mass number and Z is the atomic number)

The given reaction follow beta minus decay as:

Hence, the following nuclear reaction are balanced.

the answer is b, have negligible mass
