Anhydrous barium nitrate when heated dec...

Anhydrous barium nitrate when heated decomposes and produces `O_(2)` and `NO_(2)` gases. Similarly magnisum nitrate when heated decomposes to give out `NO_(2)` gas and oxygen. In both cases corresponding oxides are also formed. Select the correct answer(s):

A

The lattic energy value is higher for magnesium nitrate than that of barium nitrate

B

`NO_(2)` is evolved at a lower temperature in case of `Mg(NO_(3))_(2)` as compared to that `Ba(NO_(3))_(2)`.

C

`NO_(2)` will be evolved at a lower temperature in case of `Ba(NO_(3))_(2)` as compared to that of `Mg(NO_(3))_(2)`.

D

On heating `Mg(NO_(3))_(2)` and `Ba(NO_(3))_(2)`, the ratio of volume of `NO_(2)` and `O_(2)` evolved is 4:1
