Question

what happens when metal reacts with oxygen? give an example to support your answer​

Answer 1

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.

Many metals react with oxygen to form metal oxides. Potassium and sodium are soft metal which are easily cut exposing a shiny surface which changes to dull rapidly. The change from shiny to dull is called tarnishing. Potassium burns with a lilac flame when heated in air
