The nuclear reaction $_{29}^{63}Cu + _{2}^{4}He \to _{17}^{37}Cl + 14_{1}^{1}H + 16_{0}^{1}n$ is referred to as

$A$ closed vessel with rigid walls contains $1 \ mol$ of ${ }_{92}^{238} U$ and $1 \ mol$ of air at $298 \ K$. Considering the complete decay of ${ }_{92}^{238} U$ to ${ }_{82}^{206} Pb$, the ratio of the final pressure to the initial pressure of the system at $298 \ K$ is:

Which one of the following nuclear transformations is of the $(n, p)$ type?

An element ${ }_{x} A^{y}$ emits $5$ $\alpha$ and $4$ $\beta$ particles to give ${ }_{82} B^{207}$. The number of protons and neutrons in $A$ are respectively

Identify $X$ in $_{16}S^{32} + X \to _{15}P^{30} + _{2}He^{4}$.

In the nuclear reaction $_{92}U^{238} \to _{82}Pb^{206}$,the number of alpha and beta particles decayed are
