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…
Balance the following chemical equation by placing a coefficient (including 1) in each answer box that is in front of each reactant and each product. While coefficients that are equal to 1 are not placed in front of either a reactant or product, you MUST include any coefficient that is equal to 1 in this problem. type your answer...

Part A Look at the three bottles. What evidence is there that a chemical reaction took place? Part B Compare bottles 1 and 2. How do the amounts of the reactants compare? How do the amounts of the products compare? For these two bottles, does the amount of product appear to be proportional to the amount of ammonia used? Part C Compare bottles 2 and 3. How do the amounts of the reactants compare? How do the amounts of the products compare? For these two bottles, does the amount of product appear to be proportional to the amount of ammonia used? Part D Compare your answers in parts B and C. If your answers to those questions are different, explain why they’re different. Part E Imagine mixing 1 tablespoon of Epsom salt with 2 cups of ammonia. How much precipitate would be produced? Describe the amount of precipitate by comparing it with the amount in bottle 1, 2, or 3. Explain your prediction. i need them all answered please
