When `0.273g` of Mg is heated strongly in a nitrogen `(N_2)` atmosphere, `0.378g` of the compounds is formed. Hence, compound formed is

A

`Mg _(3) N _(2)`

B

`Mg _(3) N`

C

`Mg _(2) N_(3)`

D

`Mg N`

Text Solution

Verified by Experts

The correct Answer is:
A
`Mg = 0. 273 g`
Compound of Mg with `N = 0. 278 g ` N-reacted ` = 9. 105 g`

Thus, `Mg _(3) N _(2)`
