1. The reported mole ratio of magnesium to oxygen will be too high. The experiment will have less oxidation while burning. Since there are 2 oxygen and some of the magnesium evaporates as it burns, the ratio will be higher than usual
2. Since there are some magnesium present at the end of the result from not allowing all of magnesium to react and oxidize, the ratio of Mg:O will be too high
-Source of error:
The first source of error happened when students lifted the lid off, sometimes he/she accidentally opened the lid too much to check if the magnesium and the oxygen were reacting, it could cause the oxidation slower by adding more oxygen. That would make a mistake during calculation.
When opening the lid every minute, the air must have been
