- ...Reactions A.1. Reaction of Magnesium and Oxygen In the HOOD, use crucible tongs to hold the end of a piece of magnesium ribbon in the hot spot of Avert your eyes. Record your observations and write the chemical equation for this reaction if any occurred. Reaction: Mg(s) + O 2 (g) → A.2...
- When heated, magnesium reacts readily with oxygen in the air. The magnesium will be heated strongly in an open crucible for several minutes. You will measure the mass of the magnesium that reacts and the mass of magnesium oxide that is formed, and use your data to calculate the mass of the oxygen that combined. You can then find the ratio of mass of magnesium to mass of oxygen and compare your experimental ratio with the ratios of your classmates and with the actual ratio.
