CIA Demonstration: Magnesium and Dry Ice (3.1.2)

Question 1

• Magnesium readily combines with oxygen in a redox reaction, and will even pull oxygen out of carbon dioxide.

Answer 1

• Magnesium readily combines with oxygen in a redox reaction, and will even pull oxygen out of carbon dioxide.

Question 2

• The balanced chemical equation for this chemical reaction relates the amount of reactants consumed to the amount of products produced.

Answer 2

• The balanced chemical equation for this chemical reaction relates the amount of reactants consumed to the amount of products produced.

Question 3

Magnesium readily combines with oxygen in a redox
reaction.

If elemental oxygen (O2) is not available,
magnesium will react with the oxygen in dry ice
(CO2, solid).

The products of this chemical reaction are
magnesium oxide (MgO, solid) and graphite (C,
solid).

Question 4

The balanced chemical equation for this chemical
reaction relates the amount of reactants consumed
to the amount of products produced.

For every two moles of magnesium (Mg)
consumed, one mole of carbon dioxide (CO2) is also
consumed, producing two moles of magnesium
oxide (MgO) and one mole of graphite (C).
