Paragraph: Upon heating

\mathrm{KClO}_{3}

in the presence of catalytic amount of

\mathrm{MnO}_{2}

, a gas

\mathbf{W}

is formed. Excess amount of

\mathbf{W}

reacts with white phosphorus to give

\mathbf{X}

. The reaction of

\mathbf{X}

with pure

\mathrm{HNO}_{3}

gives

\mathbf{Y}

and

\mathbf{Z}

.
Question:

\mathbf{W}
