(`a`) Find `A`, `Z` and identify the nucleus `X`.
(b) Find the `Q`- value of the reaction.
`{:(m(p)=1.007825u,, m('^(15)C)=15.0106u,, m('^(16)N)=16.001u),(m('^(15)N)=15.000u,,m('^(16)O)=15.9949u,,),(m(n)=1.008665u,,m('^(15)O)=15.0031u,, 1u~~931.5MeV):}`

Explanation

To solve the nuclear reaction \( p + {}^{15}N \rightarrow {}_{Z}^{A}X + n \), we will follow these steps:

### Step 1: Identify the Reaction Components
The reaction involves:
- A proton \( p \) (which can be represented as \( {}_{1}^{1}H \))
- A nitrogen nucleus \( {}^{15}N \) (with atomic number 7 and mass number 15)
- A neutron \( n \) (which can be represented as \( {}_{0}^{1}n \))
- An unknown nucleus \( X \) with atomic number \( Z \) and mass number \( A \).
