Analysis: B) The magnesium strip had turned into a powdered form in which it has degenerated C) 37. 9 grams D) Mg – 50 / 34. 31 = 1. 45 – 1 O – 50 / 16. 0 = 3. 12 – 2 Therefore the ratio will be 1 to 2: MgO 2 E) Based on the evidence the answers are of the ones shown on the above Evaluation: F) The mass of the magnesium oxide would be far too low if there was any magnesium oxide escaping during the experiment as it causes for less particles therefore less mass to be in the container causing a lower calculation of the magnesium oxide levels.
G) The magnesium composition would have increased if it would have reacted with something else in the air as it would have spread its molecules though out a greater radius and be able to do have more molecules of magnesium which would make it heavier. H) This is necessary in order for the ribbon to be easily reachable with the heat and make the experiment both be more efficient and faster reacting. I) we can place the reaction within a large enclosed box in order to ensure not any of the mass of the oxygen or the magnesium be burned in the air without being known. Therefore at the end all of the mass will be once again retrieved to be weighed. J) The law of definite proportion is completely valid and is not broken as the experiment required oxygen and was not a closed environment experiment, needed to find exact stating mass in the end. Since the reaction took place in an open environment therefore the experiment is valid a.
