A strip of magnesium metal reacts with oxygen in the air to produce 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. 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 crucible systematic error In both trials, opening of the lid is required to read article oxygen in the surrounding air to enter the crucible, so as to react with the heated magnesium ribbon to form 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 opening the lid. This will affect the final mass taken which formual the mass of oxygen reacted with the magnesium. The fluctuation of values in electronic balance random error This is due to the small changes in mass, which are only significant in more decimal places, but are not indicated on the electronic balance.
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 powder no longer glows. However, the given magnesium ribbons even though the same length do not have the same mass, source causes the difference in the reaction time and the amount forula oxygen reacted.
The Magnesium Metal Of Magnesium Oxide
visit web page 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 escaping 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. Replicating the measurement of mass while using the electronic balance As this is a https://digitales.com.au/blog/wp-content/custom/japan-s-impact-on-japan/was-john-locke-a-deist.php error, it can be reduced by repeating the process.
The different masses should be measured multiple times at least 3 times eachand the final mass should be the average of the values measured. This can ensure a more accurate measurement. Replicating the experiment Due to time constraint, we are only able to complete two trials for this experiment.
The Formula Of Magnesium Oxide
However, more trials would be preferred, as this can minimize the random errors that occurred in the experiment, and hence improve accuracy. This might be able to prevent situation such as Trial 1, whereby the actual formula is far from the theoretical formula. Mg2O3 and MgO 4. Use an electronic balance that allow up to more decimal places As in this experiment, we are measuring very small values for masses up to two decimal places i. No references Related Papers.]
