Yes, it will because iodine is less reactive than chlorine.
Yes, it will because iodine is less reactive than chlorine.

No, it will not because iodine and chlorine will not bond.

No, it will not because iodine is less reactive than chlorine.
No, it will not because iodine is less reactive than chlorine.

Yes, it will because the iodine will replace the magnesium.

Answer 1

The correct response is:

Yes, it will because iodine is less reactive than chlorine.

In this reaction, chlorine (Cl₂) is more reactive than iodine (I₂). Therefore, chlorine can displace iodine from magnesium iodide (MgI₂), resulting in the formation of magnesium chloride (MgCl₂) and elemental iodine (I₂). The reaction can be represented as follows:

\[ \text{MgI}_2 + \text{Cl}_2 \rightarrow \text{MgCl}_2 + \text{I}_2 \]

This makes it clear that the reaction will occur since a more reactive halogen (chlorine) can replace a less reactive halogen (iodine).
