Observations: Magnesium ribbon burns with dazzling light and white substance is formed which is magnesium oxide. This happens due to following chemical reaction: 2Mg(s) + O2 (g) ====> 2MgO (s)

Results: Burning of magnesium in presence of oxygen to form magnesium oxide is a combination reaction.

The flame provides a source of heat so that the magnesium metal atoms can overcome their activation energy. Activation energy is the minimum energy required in order for a chemical reaction to proceed. When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide.
