Well, "reaction 1" is.........

Explanation:

Redox reactions involve a formal change in oxidation number........

And if we superscript the oxidation numbers..........

stackrel(0)"Mg" +stackrel(0)"Cl"_2(g)rarrstackrel(+II)"Mg"stackrel(-I)"Cl"_2

The metal has been (typically) oxidized, and has donated electrons to the non-metal, and thus reduced it..........

Can you write the individual half equations representing formal oxidation and reduction?
