Vedclass · Answer

(B) The thermal decomposition of metal nitrates follows specific patterns based on the reactivity of the metal.For $P$: $AgNO_3 \xrightarrow{\Delta } Ag (	ext{metallic solid}) + NO_2 \uparrow + \frac{1}{2} O_2 \uparrow$.For $X$: $Pb(NO_3)_2 \xrightarrow{\Delta } PbO (	ext{amphoteric oxide}) + 2 NO_2 \uparrow + \frac{1}{2} O_2 \uparrow$.Thus,$P$ is $AgNO_3$ and $X$ is $Pb(NO_3)_2$.
