Question

Write down the experimental procedure to know how metals and non-metals react with oxygen.

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.
