The Magnesium Metal Of Magnesium Oxide

In order to experimentally determine the percentage composition and empirical formula of magnesium oxide, a piece of magnesium is heated strongly to react with the oxygen in the air. magnesimu
The reaction of magnesium with oxygen occurs relatively slowly, so a Bunsen burner will be used to enable the reaction to take place more quickly. While Trial 2 is better as I had empirical formula MgO as my result, and the percentage error, which is However, the average total percentage uncertainty is very high On comparing these two errors, the result in trial 2 is much accurate than that in Trial 1. This is because the answer is the same as the theoretical formula of MgO. Evaluation: The main significant sources of errors may come from: 1. The opening of the lid allows white ashes MgO to escape from the empirical formula of the oxide of magnesium systematic error In both trials, opening of the lid is required to allow oxygen in the surrounding air to enter the crucible, so as to react with the heated magnesium ribbon to form magnesium oxide.
The Formula Of Magnesium Oxide
However, white ashes MgO escapes from the crucible due to the strong heat, causing the convectional air in the crucible, which blows out the magnesium oxide while empirical formula of the oxide of magnesium the lid. This will affect the final mass taken which determines the mass of oxygen reacted with the magnesium.
However, this affects the value shown on the electronic balance as rounding off is required in the machine. The duration of heating the magnesium ribbon random error From the instructions given, we are told to stop the heating only when the link no longer glows. However, the given magnesium ribbons even though the same length do not have the same mass, hence causes the difference in the reaction time and the amount of oxygen reacted. However, these changes are very small for example; 0.
Improvement: 1. Quickly close back the lid after allowing some oxygen to enter the crucible This is because white ashes MgO will escape while opening the lid during heating. Therefore, to minimize the amount of MgO pxide the crucible, it is best to quickly close back the lid after allowing some of the oxygen in the surrounding to enter the crucible, to react with the magnesium ribbon.]
