1)take about 3 cm long piece of magnesium ribbon.
2)Rub the magnesium ribbon with sand paper.
3)Hold with pair of tongs.
4)Burn it with a spirit lamp /burner.
5)Magnesium burns in oxygen by producing dazzling white flame & changes into white powder(Magnesium Oxide).
6)2Mg +O2 =2MgO(s)
7)in this reaction magnesium &oxygen combine to form a new substance magnesium oxide.
8)A reaction in which single product is formed from 2 or more reactants is known as chemical recombination reaction.

Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.
