Answer 1

Answer:

When a metal reacts with oxygen, a metal oxide forms. The general equation for this reaction is: metal + oxygen → metal oxide. Rust is a form of iron oxide and it forms slowly when iron is exposed to air. Iron can be transformed to steel (an alloy), which is more resistant to rust.
