🔥 Burning magnesium ribbon in a CO2 atmosphere results in a reaction where magnesium is oxidized and CO2 is reduced.
⚪️ The reaction produces magnesium oxide and free carbon (soot).
⚫️ Squeezing the burning magnesium against the beaker wall leaves a black carbon stain.
🔥 The reaction of magnesium with CO2 produces carbon residues.
⚪ Combustion of magnesium in air produces a whiter ash.
✨ Burning magnesium with pure oxygen increases the brightness of the reaction.
