Answer:
Magnesium ribbon burns in the air to form Magnesium oxide. This is a combination reaction as two reactants combine to form a single product.
When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide.
Oxygen and magnesium combine in a chemical reaction to form this compound.
After it burns, it forms a white powder of magnesium oxide.
Magnesium gives up two electrons to oxygen atoms to form this powdery product.
