Solution:

When P4 is treated with N2O (O.S = 1) it produces P4O10 and N2 (diatomic molecule).
P4O10 used as dehydrating agent
$\left(\text{P}\right)_{4} & + & 10\left(\text{N}\right)_{2}\text{O} & \rightarrow & \left(\text{P}\right)_{4}\left(\text{O}\right)_{1 0} & + & 10\left(\text{N}\right)_{2} \\ \left(\text{X}\right) & & & & \left(\text{Y}\right) & & \left(\text{Z}\right)$
