Answer 1

$\texttt{Compound P is Sodium hydroxide (NaOH).}$

$\texttt{Compound Q is Water} \mathtt{ (H_{2}0).}$

$\texttt{Compound R is Calcium oxychloride or}$

$\texttt {bleaching powder} \mathtt{ (CaOCl_{2}).}$ to

$\texttt {X is Hydrogen gas} \mathtt{ (H_{2}).}$

$\texttt {Y is Chlorine gas} \mathtt{ (Cl_{2}).}$

$\mathtt{2NaCl + 2H_{2}O} \rightarrow \mathtt{2NaOH + Cl_{2} + H_{2} }$

$\mathtt {Ca(OH)_{2} + Cl_{2}} \rightarrow \mathtt { CaOCl_{2} + H_{2}O}$
