Magnesium ribbon is cleaned before burning because to remove the basic layer of magnesium oxide and magnesium carbonate that has formed on the surface of the ribbon due to reaction of magnesium with oxygen and carbon dioxide . By cleaning the magnesium ribbon with sand paper, the ribbon burns smoothly. 2Mg + O2 ------> 2MgO and Mg + CO3 -------> MgCO3
