The change in mass when magnesium burns | Experiment …
This should allow them to calculate the mass of the mass of the magnesium (mass 2 – mass 1) and the mass of the product (mass 3 – mass 1). They could also calculate the increase in mass (mass 3 – mass 2), which corresponds to the mass of oxygen. The equation is: Magnesium + oxygen → magnesium oxide. 2Mg + O 2 → 2MgO.
