Magnesium Ribbon when Burnt in Presence of Air Produces: (a) Magnesium oxide, water and light. (b) magnesium oxide and heat. (c) magnesium oxide, heat and light. (d) magnesium oxide, water and heat

Answer: (c) magnesium oxide, heat and light.

Explanation:

Magnesium ribbon when burnt in the presence of air, it reacts with oxygen in order to produce white powder, combined to form magnesium oxide (MgO) along with production of heat and light. It forms a white powder of magnesium oxide.

Magnesium donates 2 electrons to the oxygen atom, to form the result of this powder.

2Mg + O2⟶ 2MgO
