Procedure This lab was started by first weighing the Crucible and the lid that are being used in grams, after they have both sat over a Bunsen burner to burn off an excess materials from any usage before. Students set out to find if a ratio of 1: An empirical formula is the ration of atoms in a compound.
A synthesis reaction is when at least two or more substances combine to form a single product. The percentage composition of magnesium will stay same even though some of the magnesium oxide has lost.
In this instance the two reactants that were apparent are Magnesium, and Oxygen. After all the smoke had disappeared and the crucible was left to cool for five minutes, the Crucible and all of its contents were measured again.
This was then measured again and turned out to be slightly heavier than the measurement before. In order to solve this problem the experiment would have done in glass box with two openings. More over while magnesium was kept in laboratory or open place it would have reacted with other particles of air or some chemicals in laboratories.
This added weight is Oxygen, forming the combustion of Magnesium Oxide. First of all, we just proved that no matter what the mass is, every time oxygen combines with magnesium to form Magnesium oxide, the percentage composition of both elements will stay same.
Other way, if some of the Magnesium oxide has escaped it would have been escaped in Percentage composition of MgO for classmates Name of group or procedure Percentage composition for Mg Percentage composition for O Relatively related to the required?
The final weighing of the crucible with the magnesium should weigh more, due to the oxygen combining with magnesium to form Magnesium Oxide. This caused us to run out of time for further steps of experiment. Aditi, Manmeet and Kamaljit After the previous step was completed, the crucible and the Magnesium were heated until white smoke started to protrude from with the crucible.
