Question

when magnesium ribbon burns in air or oxygen a product is formed state the type of chemical reaction and name the product formed in the reaction write a balanced chemical equation for this reaction

Answer 1

When Magnesium ribbon burns in presence of oxygen, we could observe a dazzling white flame and a white substance is formed which is magnesium oxide. The reaction is a combination reaction.
   2Mg + O2 = 2MgO

Answer 2

When we burn any substance in the presence of atmospheric oxygen,an oxidation happens and generally an oxide substance is generated.

Similarly when we burn the magnesium in the atmospheric oxygen,a white coloured substance is generated which is known as the magnesium oxide.

The chemical equation of this reaction is ;

2Mg+O2= 2MgO [white]
