Question

Reaction of metal with oxygen:
Give 5 points:​

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.

Answer 2

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.
