Why should magnesium ribbon be cleaned before burning in air?

Solution
Magnesium ribbon must be cleaned before burning in the air because:-
- A layer of magnesium oxide(MgO) is formed on the ribbon due to the reaction of magnesium(Mg) with air, slowing down or interfering with the burning process.
- So, it is cleaned in order to get the desired chemical reaction i.e., 2Mg(s) + O2(g) ⟶ 2MgO(s)
