Rust

#### Explanation:

Wood is made chiefly of cellulose (Carbon, Hydrogen & Oxygen)

Nails are made from Iron / steel (and can be galvanised)

Rust is made when iron reacts with oxygen!

The reaction(s) are as follows (in reality, the first reaction occurs and then the FeO reacts further with oxygen to produce the final product);

$2 F e + {O}_{2} \to 2 F e O$
$4 F e + 3 {O}_{2} \to 2 F {e}_{2} {O}_{3}$
