Students conduct an investigation to synthesize magnesium oxide by burning a strip of magnesium in the presence of oxygen in the air. A bunsen burner is used to heat the crucible containing the magnesium until it burns with the air inside the crucible. The students leave the lid slightly open to keep the magnesium oxide inside but allow air to come in to completely finish the reaction. A diagram of the experimental setup is shown below.
