Burning is a chemical process, not a property.
Magnesium ribbon is cleaned with the sand paper before use because its surface is covered with certain type of grease, in the presence of which the Mg cannot work proper and faster.
No, magnesium ribbon are not pure. They have to be rubbed with sand paper, this removes the impurities on them
MENOR!
Magnesium is an extremely reactive metal. When stored, it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper for removing this layer so that the underlying metal can be exposed to air.
