Answer:
When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. ... After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.
And SI unit of pressure is pascal
