Formation of Magnesium oxide Lab

Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg2+ ions and O2− ions held together by ionic bonds. Magnesium is one of the alkaline-earth metals, and is one of the most common elements in the Earth's crust.   In its pure form, it is silvery white, and relatively soft.   It burns in air with a brilliant white light, and for this reason is often used in flares and fireworks. When magnesium is in its metal form it will burn very easily in air. However, in order to start the reaction (the burning) the magnesium metal needs a source of energy. 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. Oxygen and magnesium come together in a synthesis reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product which is a form of synthesis reaction.
Balanced chemical equation ---- 2 Mg (s) + O2 (g) → 2 MgO (s)
Couple of changes should occur after the magnesium is burned and magnesium oxide is formed. The mass of the magnesium should increase after the process of burning and becoming magnesium oxide. The increase in mass is due to the fact that oxygen from the air has combined with the magnesium to make magnesium oxide and that will cause a combination between the mass of the oxygen and the mass of the magnesium that is used in the experiment.   The color of the of the magnesium changes after its burned and turns into a white solid mineral...
