Answer 2

Answer:

Magnesium burns so bright because the reaction releases a lot of heat. As a result of this exothermic reaction, magnesium gives two electrons to oxygen, forming powdery magnesium oxide (MgO).

The ribbon burns with a bright white light. Intense heat is also produced in this reaction. Here, when magnesium burns, it reacts with the oxygen found in air to form a powdery ash called magnesium oxide.
