Vedclass · Answer

(A) Heating $(NH_4)_2Cr_2O_7$ results in the evolution of nitrogen gas: $(NH_4)_2Cr_2O_7 \xrightarrow{\Delta} N_2 + Cr_2O_3 + 4H_2O$. $KClO_3$ decomposes to give $KCl$ and $O_2$. $NaNO_3$ decomposes to give $NaNO_2$ and $O_2$. $K_2Cr_2O_7$ decomposes to give $K_2CrO_4$,$Cr_2O_3$,and $O_2$. Therefore,$(NH_4)_2Cr_2O_7$ is the compound that does not release oxygen upon heating.
