The products are iron and magnesium oxide. This is a single displacement reaction.

#### Explanation:

Magnesium is above iron in the electrochemical series, so it can displace iron from its compounds.

The equation is

"Fe"_2"O"_3 + "3Mg" → underbrace("3MgO")_color(red)("magnesium oxide") + underbrace("2Fe")_color(red)("iron") #

We call this a single displacement reaction because one atom ($\text{Mg}$) displaces another atom ($\text{Fe}$) as a partner of the $\text{O}$ atom
