Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Reaction of magnesium or calcium with oxygen gives magnesium oxide or calcium oxide. 2Mg+O2From air⟶2MgO Reaction of magnesium or calcium with nitrogen gives Mg3N2 or Ca3N2. The chemical reaction is as follows. 3Mg+N2From air⟶Mg3N2 Hence, metal…
