Answer 2

1. what is rust=Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides and iron(III) oxide-hydroxide, and is typically associated with the corrosion of refined iron.
2. write the chemical formula of rust=it is estimated that about one-seventh of all iron production goes to replace the metal lost to corrosion. Rust is apparently a hydrated form of iron(III)oxide. The formula is approximately Fe2O3•32H2O, although the exact amount of water is variable
