Answer:

When a magnesium ribbon is heated, it burns in air with a dazzling white flame to form a white powder called magnesium oxide. Actually, on heating, magnesium combines with oxygen present in air to form magnesium oxide...

 Magnesium    +    Oxygen                           Magnesium oxide                           

(As ribbon)          (From air)         ⇒               (white powder)

                                 OR

 Mg  +  O_{2}O2     ⇒   MgO
