Answer: The balanced nuclear equations are given below.
Explanation:
Beta-decay is defined as the decay process in which a neutron gets converted to a proton and an electron. The electron released during this process is considered as a beta particle only.
The general reaction representing beta decay process is:
[tex]_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta[/tex]
For the beta decay reactions of the given nucleides, we get:
For A: Nitrogen-16
[tex]_7^{16}\textrm{N}\rightarrow _{8}^{16}\textrm{O}+_{-1}^0\beta[/tex]
For B: Potassium-40
[tex]_{19}^{40}\textrm{K}\rightarrow _{20}^{40}\textrm{Ca}+_{-1}^0\beta[/tex]
Thus, the balanced nuclear equations are given below.
