Question

Discuss reaction of metal with air (oxygen)?​

Answer 1

$\huge\color{blue}{Answer❤}$

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.

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.

Answer 2

Answer:

Metals react with oxygen to form metal oxides.

Metal oxides are basic in nature

METAL + OXYGEN ......... METAL OXIDE

Example :

2Cu + O2 .......2CuO
