Chemistry AT1 Christopher Baziwe 11OL Investigating the formula of magnesium oxide Aim Investigating the relationship between the mass of magnesium oxide formed when magnesium is burnt in air and how this relates to the accepted formula for magnesium oxide. Intro 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. From the diagram below we can see how magnesium reacts with oxygen, the way it shares its electrons by ionic bonding. Magnesium + Oxygen Magnesium Oxide Mg + O MgO In this experiment e are trying to find out the relationship between the mass of magnesium oxide formed...
