. Magnesium burns in oxygen to form magnesium oxide. However, when magnesium burns in air, which is only about 1/5 oxygen, side reactions form other products, such as magnesium nitride, Mg3N2 . a. Write a balanced equation for the burning of magnesium in oxygen. b. If enough magnesium burns in air to produce 2.04 g of magnesium oxide but only 1.79 g is obtained, what is the percentage yield? c. Magnesium will react with pure nitrogen to form the nitride, Mg3N2 . Write a balanced equation for this reaction. d. If 0.097 mol of Mg react with nitrogen and 0.027 mol of Mg3N2 is produced, what is the percentage yield of the reaction?
