Write any 2observations while burning magnesium ribbon in air

1.	Write any 2observations while burning magnesium ribbon in air
Answer» Observations: Magnesium ribbon burns with dazzling light and white substance is formed which is magnesium oxide. This happens due to following chemical reaction: 2Mg(s) + O2\xa0(g) ====> 2MgO\xa0(s)Results: Burning of magnesium in presence of oxygen to form magnesium oxide is a combination reaction. The flame provides a source of heat so that the magnesium metal atoms can overcome their activation energy. Activation energy is the minimum energy required in order for a chemical reaction to proceed. When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide.
