. 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?

Listenbase your answer to the question on the information below. nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body. cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment. which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
