Question

How oxygen react with metals and non metals

Answer 1

Non-metals react with oxygen in the air to produce non-metal oxides. Here are two examples for the non-metals carbon and sulphur.

EG: Carbon burns in air to form carbon dioxide:

carbon + oxygen → carbon dioxide

Sulphur burns in air to form sulphur dioxide:

sulphur + oxygen → sulphur dioxide

Metals react with oxygen to form metal oxides.These metal oxides are basic in nature.

EG:  Metal + Oxygen = Metal Oxide .

1)When magnesium burns in air,it combines with the oxygen of air to form magnesium oxide(basic oxide) .

2)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.This iron oxide is rust.

EG: Magnesium +oxygen ——–> Magnesium Oxide.
