Question

4. What happens when metals react with oxygen and water?
Also write chemical equations involved.​

Answer 1

Answer:

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.

Answer 2

Metal + oxygen = metal oxide which is basic in nature ( turns red litmus blue )
Metal+ Water = metal hydroxide which is acidic in nature ( turns blue litmus red )
