Give example for the following: Reaction of oxygen with a metal.

Metals react with oxygen to form basic oxides. One such example is the burning of magnesium metal which gives magnesium oxide. 2 Mg + O 2 → 2 MgO

Give example for the following: Reaction of oxygen with a non-metal.

Non-metals combine with oxygen to form acidic oxides, in some cases neutral oxides are also formed. For example, carbon reacts with oxygen to form carbon dioxide. C + O 2 → CO 2

Give example for the following: Sources of water vapour in nature.

Water vapour is present in the air which is called humidity. These vapours are the result of the evaporation of surface water like rivers, seas, and lakes, and transpiration from plants.

Give examples for the following: Sources of dust particles in the air.

Dust particles are attained in the air by the uplifting of soil particles and the construction sites. These are the particulate impurities.
