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.

How do metals react with oxygen explain with an example?

Metals react with oxygen to form metal oxides. These metal oxides are basic in nature. Magnesium oxide dissolves in water to form magnesium hydroxide solution. ... 3)During the rusting of iron,iron metal combines slowly with the oxygen of air in the presence of water to form a compound called iron oxide.

How does metals react with oxygen and water?

Metals react with water and produce a metal oxide and hydrogen gas. Metal oxides that are soluble in water dissolve in it to further form metal hydroxide.
