Vedclass · Answer

(C) Let us analyze the thermal decomposition of each compound:$I$. $2AgNO_3 \xrightarrow{\Delta} 2Ag + 2NO_2 + O_2$$II$. $CaCO_3 \xrightarrow{\Delta} CaO + CO_2$ (Does not give $O_2$)$III$. $2Pb(NO_3)_2 \xrightarrow{\Delta} 2PbO + 4NO_2 + O_2$$IV$. $Na_2CO_3$ is thermally stable and does not decompose to give $O_2$.Thus,compounds $I$ and $III$ release oxygen gas upon heating. However,checking the provided options,the question implies identifying which compounds release oxygen. Based on the chemical reactions,only $I$ and $III$ produce $O_2$. Since this specific combination is not explicitly listed as a single option,we re-evaluate the question context. If the question intended to ask for nitrates,the answer would be $I$ and $III$. Given the options provided,there might be a typo in the question's options. Assuming the question asks for compounds that release oxygen,the correct set is $I$ and $III$.

Which of the following compounds gives oxygen on fast heating?
$I$. $AgNO_3$
$II$. $CaCO_3$
$III$. $Pb(NO_3)_2$
$IV$. $Na_2CO_3$
