Question

Does the burning of magnesium ribbon in air involve any liberation of energy ? If yes, in what form

Answer 1

Answer:

When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. ... Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction as well as combination reaction

Answer 2

The burning of a magnesium ribbon does involve the liberation of energy.

• As the magnesium metal burns, it reacts to Magnesium Oxide forming with oxygen present in the air. It also results in the production of bright light as lot of heat is produced.
• During the process, for the formation of a powdered product, the oxygen atoms are given by magnesium to two electrons. The reaction carried out is both a combination and an exothermic reaction.
