Question

what happen when metal react with oxygen give two example​

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.

hope it's help u :-)

Answer 2

Metals react with oxygen to form basic oxides. Metallic oxides are basic in nature because they react with dilute acids to form salt and water. They also react with water to form metal hydroxides which are alkaline in nature because these metal hydroxides release OH− ions in solution.
