When during the reaction of magnesium should you place the cover on the crucible?
The instant that the magnesium starts to burn, put the cover on the crucible (using the crucible tongs) to put out the fire. 9. Continue heating the covered crucible for a minute or so, then take off the cover again.

Why was the mass of the magnesium measured before starting the experiment?
Since the mass of magnesium is recorded before the reaction, the percent composition of magnesium in the final product will be higher. If you performed this experiment correctly, you’ll get the percent of magnesium in magnesium oxide to be around 60%, more or less depending on how you did the experiment.
What is the mass of magnesium?
24.305 u
Magnesium/Atomic mass
Why is magnesium oxide heavier than magnesium?
The increased mass is because of oxygen. Magnesium oxide has the formula of mgo according to the ratio between the moles of magnesium and oxygen in the final product.
Why is the crucible lid lifted when magnesium is heated?
The crucible is placed on a clay triangle on a tripod and is heated strongly. The lid is lifted at intervals to allow the oxygen from the air to enter for the combustion of magnesium from escaping by closing the lid immediately after it is lifted.
