what happens when magnesium ribbon is heated? |
| Magnesium ribbon burns in air with an extremely bright white light, giving off a large amount of energy, and white smoke with is mostly magnesium oxide in very fine particles. The magnesium ribbon easily crumbles into a white powder which is a mixture of magnesium oxide (about 90%) and magnesium nitride (about 10%). since air is a mixture of oxygen and nitrogen gases, both elements react with the magnesium metal. 2Mg +O2------->2MgO |
