| (Q) P4 + 3NaOH + 3H2O | (2) H3PO3 |
| (R) PCl5 + CH3COOH | (3) PH3 |
| (S) H3PO2 + 2H2O + 4AgNO3 | (4) POCl3 |
| (5) H3PO4 |

Explanation
$\begin{aligned} & \mathrm{P}_2 \mathrm{O}_3+3 \mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{H}_3 \mathrm{PO}_3, \quad\mathrm{P} \longrightarrow 2 \\\\ & \mathrm{P}_4+3 \mathrm{NaOH}+3 \mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{PH}_3+\mathrm{NaH}_2 \mathrm{PO}_2, \quad\mathrm{Q} \rightarrow 3\end{aligned}$
$\begin{aligned} & \mathrm{PCl}_5+\mathrm{CH}_3 \mathrm{COOH} \longrightarrow \mathrm{CH}_3 \mathrm{COCl}+\mathrm{POCl}_3, \quad \mathrm{R} \rightarrow 4 \\\\ & \mathrm{H}_3 \mathrm{PO}_2+2 \mathrm{H}_2 \mathrm{O}+\mathrm{4AgNO}_3 \longrightarrow \mathrm{H}_3 \mathrm{PO}_4+\mathrm{Ag}+\mathrm{HNO}_3, \quad \mathrm{~S} \rightarrow 5\end{aligned}$
$\begin{aligned} & \mathrm{PCl}_5+\mathrm{CH}_3 \mathrm{COOH} \longrightarrow \mathrm{CH}_3 \mathrm{COCl}+\mathrm{POCl}_3, \quad \mathrm{R} \rightarrow 4 \\\\ & \mathrm{H}_3 \mathrm{PO}_2+2 \mathrm{H}_2 \mathrm{O}+\mathrm{4AgNO}_3 \longrightarrow \mathrm{H}_3 \mathrm{PO}_4+\mathrm{Ag}+\mathrm{HNO}_3, \quad \mathrm{~S} \rightarrow 5\end{aligned}$
