• The Layer Of Magnesium Oxide Which Is Formed Due To Reaction Of Magn

Explanation:

• The magnesium ribbon should be cleaned before burning in the air because the layer of magnesium oxide (which is formed due to the reaction of magnesium with air ) can be removed in order to get the desired chemical reaction.
• Also in order to remove the oxide layer, the presence of which slowdowns the oxidation process. So, by cleaning it, the burning process takes place easily.

let more explanation:

Magnesium is very reactive metal . when it is kept in the open air it can react with the gases present in the air. cleaning will remove those impurities formed due to reaction with gases.

Magnesium is a akaline earth metal ,' akaline period' means materials are which in second group of the periodic table are called the akaline period.
