Question

Magnesium ribbon is burnt in the presence of nitrogen gas to form solid magnesium nitride.
How is this reaction a redox reaction ????

Answer 1

Answer:

Explanation:

on mg reacting with n2 . mg losses its electrons hence mg undergoes oxidation and nitrogen gas gains the electrons lost by mg hence n2 under goes reduction .

                                Mg ⇒ Mg+2     +      2e-

                                 N2  +  6e- ⇒  2N3-
