# What type of chemical reaction is 4Fe + 3O_2 -> 2Fe_2O_3?

This is clearly an oxidation reaction.

#### Explanation:

Zerovalent iron is oxidized to give $F e \left(I {I}^{+}\right)$. Zerovalent oxygen is reduced from $0$ to $- I I$. Each year significant amounts of money are spent to prevent the corrosion of structural steel. It is inevitably a losing battle.
