Vedclass · Answer

(A) Sodium nitrate $(NaNO_3)$ decomposes upon heating. At temperatures up to $500 \, ^oC$,it decomposes to form sodium nitrite and oxygen: $2NaNO_3 \rightarrow 2NaNO_2 + O_2$. However,at temperatures above $800 \, ^oC$,sodium nitrite further decomposes to form sodium oxide,nitrogen,and oxygen: $4NaNO_2 \rightarrow 2Na_2O + 2N_2 + 3O_2$. Thus,the final products at temperatures above $800 \, ^oC$ include $N_2$.

The decomposition of sodium nitrate at temperatures above $800 \, ^oC$ yields ...............
