Answer:
When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. 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 as well as combination reaction.
2Mg(s)+O

Answer:
ab magnesium ribbon whether coating of magnesium oxide would not burn because magnesium oxide is an ionic compound and we know that ionic compound are having very high melting points that is the reason the magnesium metal would not be exposed to oxygen that is the reason why it is wrapped before burning
