1.	Which of the following metal nitrate on heating does not give its metal Oxide?
Answer» `NaNO_(3)` `Mg(NO_(3))_(2)` `CA(NO)_(3)` `LiNO_(3)` SOLUTION :(B) `2MG(NO_(3))_(2(s)) overset(Delta)to 2MgO_((s))+4NO_(2(g)) +O_(2(g))` (C ) `2Ca(NO_(3))_(2(s)) overset(Delta)to 2CaO_((s)) +4NO_(2(g)) +O_(2(g))` (A) `NaNO_(3(s)) overset(Delta)to 2NaNO_(2(s))+O_(2(g))` (D) `4LiNO_(3(s)) overset(Delta)to 2Li_(2)O_((s)) +4NO_(2(g)) +O_(2(g))` `NaNO_(3)` does not form OXIDE but gives `NaNO_(2)` (nitrite) on heating.
