Answer»

In the ELECTROLYTIC cell when fuse `MgCl_(2)` is subjected to electrolysis
when fused `MgCO_(3)` is heated
when fused `MgCO_(3)`is strongly heated
none of the above

Solution :In the electrolytic cell, when fusd `MgCl_(2)` is subjected to electrlysis
At Anode `2CI^(-) to Cl_(2) +2e^(-)` (Oxidation) : At CATHODE `:MG^(2+)+2e^(-) to Mg` (Reduction)
