Question Question 1
Why should a magnesium ribbon be cleaned before burning in air?
As magnesium is a very reactive metal hence it reacts with oxygen and a layer of magnesium oxide is formed on its surface, which prevents further reaction of magnesium with oxygen. Therefore, magnesium ribbon is cleaned before burning in air.
