Mention the action of oxygen with the elements sulphur, phosphorus, sodium and magnesium. |
|
Answer» Solution :(i) Reaction with sodium (NA): Sodium reacts with `O_(2)` vigorously at room temperature to form sodium OXIDE `4Na_(2)+O_(2)to2Na_(2)O` (ii) Reaction with magnesium(Mg): Magnesium reacts with oxygen upon slight heating to form magnesium oxide `2Mg+O_(2)to2MgO` (iii) Reaction with sulphur: Sulphur when HEATED in an atmosphere of oxygen, burns to form sulphur DIOXIDE. `S+O_(2)toSO_(2)` (IV) Reation with phosphorus: When phosphorus is heated in an atmosphere of oxygen it burns to produce phosphorus pentioxide. `4P+5O_(2)to2P_(2)O_(5)` |
