The balanced equation for this reaction can be used to construct two unit factors that describe the relationship between the amount of magnesium and oxygen consumed in this reaction. Practical Chemistry activities accompanyPractical PhysicsandPractical Biology. Learn more about Stack Overflow the company, and our products. Note that all masses should be determined tofour decimal placeson the electronic balance: this results in typically 6 significant figures when the masses of containers are included, which provides for the masses of magnesium and magnesium oxide to be determined to four significant figures. There are multiple reasons why a reaction would happen at high temperatures but not at low temperatures: For all but the first, it does not matter whether the reaction is endothermic or exothermic - higher temperature helps or is required to observe a reaction. Alternatively, light one or two Bunsens around the room and students can light their own using a splint. Based on the predicted formula of magnesium oxide (part h above), we can calculate the "theoretical" percent by mass of magnesium in magnesium oxide.
