REACTION OF METALS WITH OXYGEN
Metal + oxygen -->metal oxide
Rusting of iron is the formation of iron oxide when iron reacts with moisture and oxygen in the atmosphere and produces iron oxide which is known as rust
Iron +oxygen +water-->iron oxide(iron oxide is also known as ferrous oxide )
(NOTE:- Burning is reacting with oxygen when metals are burned means it reacts with oxygen and produces metal oxide )
Eg:- magnesium burns in the air with a dazzling white flame and white ashes are produced that white ashes are magnesium oxide
Metal oxides are basic in nature. Metal oxide which is soluble in water turns red litmus blue. Magnesium oxide mixed with water turns red litmus blue
Magnesium oxide + water——> magnesium hydroxide
MgO + H₂O——> Mg(OH)₂
