Vedclass · Answer

(A, B, D) Sodium nitrate $(NaNO_3)$ decomposes upon heating.At temperatures up to $500\,^oC$,it decomposes to form sodium nitrite and oxygen: $2NaNO_3 \rightarrow 2NaNO_2 + O_2$.At temperatures above $800\,^oC$,sodium nitrite further decomposes to form sodium oxide,nitrogen,and oxygen: $2NaNO_2 \rightarrow Na_2O + N_2 + 1.5O_2$.Therefore,the final products at temperatures above $800\,^oC$ include $N_2$,$O_2$,and $Na_2O$.

What is obtained by the decomposition of sodium nitrate at temperatures above $800\,^oC$?
