Here is some information to help. In this experiment, magnesium metal is heated until it reacts with oxygen in the air according to the following balanced equation: 2Mg(s)+ O2(g) → 2MgO(s) (silver metal) (white-gray ash) As the magnesium burns in air, it may also combine with nitrogen in air. To remove any nitride product, water is added, and the product is reheated. Any nitride product is converted to magnesium oxide and ammonia. 3Mg(s)+ N2(g) → Mg3N2(s) Mg3N2(s)+3H2O(l)→3MgO(s)+2NH3(aq) A weighed amount of the magnesium metal is used, and the mass of the oxide product formed is determined at the end of the experiment. The mass of oxygen that combines with the magnesium is obtained from the difference between the mass of the oxide product and the original mass of magnesium. mass of oxide product-mass of magnesium=mass of oxygen in oxide product The empirical formula of the oxide…

One day in lab, while adding a gnarled root to a dark liquid bubbling in an iron cauldron, your friend Raina (an expert chemist) says this: "Many metals can be produced from their oxide ores by reaction at high temperatures with carbon monoxide. Carbon dioxide is a byproduct." Using Raina's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced!
