Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Mg and Ca, on burning in air, form both oxides and nitrides:
$\text{Mg} + \text{O}_2 \to \text{MgO}$, \quad $\text{Mg} + \text{N}_2 \to \text{Mg}_3\text{N}_2$
Similarly for Ca.
$\text{Mg} + \text{O}_2 \to \text{MgO}$, \quad $\text{Mg} + \text{N}_2 \to \text{Mg}_3\text{N}_2$
Similarly for Ca.
