Prove this reaction is a redox reaction 3 Mg + 2 FeCl3 +2 Fe + 3 MgCl2

Your answer should include the half equations

because Redox means two words:reduction and oxidation

reduction is when oxygen is taken from a substance while oxidation is the addition of oxygen to a substance..Magnesium displaces chlorine from iron(fe)because it is more reactive than iron

and iron gives chlorine to magnesium because it's less reactive.This is due to their position on reactivity series.

Explanation:

This is called displacement reaction where by A most reactive metal remove a substance from a less reactive metal and form up a salt

and in this case the salt formed in the reaction is 3MgCl
