(i) The product of this reaction is – MgCl₂

(ii) The balanced equation for the complete reaction is : -

Mg_(s) + Cl_2(g) → MgCl_2(s)

(iii) In this reaction magnesium is the element which is being oxidised as it is losing two electrons and gets converted to a stable cation Mg²⁺.

(iv) In this reaction chlorine is the element which is getting reduced as the two chlorine atoms accepts one electron each and gets convert into anion Cl^-.

(v) Reduction part of the reaction is : -

2Cl + 2e^-→ 2Cl^-
