Answer» 1)Answer:Magnesium ribbon mustbe cleanedbefore burning in air so that the layer ofmagnesiumoxide (which is formed due to reaction ofmagnesium with air) can be removed in order to get the desired chemical reaction. it is because there is oxide layer on magnesium which must be removed ,otherwise it will react very slowly Magnesium ribbon be cleanes before burning because ribbon clean from small particles of sand,etc. So magnesium speedly contact with oxegen when burning |
