Reaction of Metals with Oxygen

• What should you be able to describe by the end of the video?

  How metals react with oxygen
• What is the significance of the reaction of metals with oxygen?

  It involves oxidation and reduction processes
• What is the outcome when metals react with oxygen?

  • Formation of metal oxides
  • Example: Magnesium + Oxygen → Magnesium Oxide
  • Example: Iron + Oxygen → Iron Oxide
• How does magnesium react with oxygen?

  Magnesium reacts rapidly, releasing a great deal of heat and light
• How does iron react with oxygen compared to magnesium?

  Iron reacts more slowly, taking weeks or months to react
• What is formed when a metal reacts with oxygen?

  A metal oxide is formed
• What is the chemical equation for the reaction of magnesium with oxygen?

  Magnesium + Oxygen → Magnesium Oxide
• What is the chemical equation for the reaction of iron with oxygen?

  Iron + Oxygen → Iron Oxide
• What is oxidation in the context of metal reactions with oxygen?

  Oxidation is the gain of oxygen by the metal
• In the reaction of magnesium with oxygen, what happens to magnesium?

  Magnesium is oxidized as it gains oxygen
• In the reaction of iron with oxygen, what happens to iron?

  Iron is oxidized as it gains oxygen
• What happens during a reduction reaction in metal compounds?

  • Oxygen is removed from the metal compound
  • Example: Magnesium Oxide → Magnesium + Oxygen
  • Magnesium atoms lose oxygen
• What is the reaction of magnesium oxide when it is split back into elements?

  It produces magnesium and oxygen
• What is reduction in the context of metal reactions?

  Reduction is the loss of oxygen from the metal
• In the reaction of calcium with copper oxide, which element is oxidized?

  Calcium is oxidized as it gains oxygen
• In the reaction of calcium with copper oxide, which element is reduced?

  Copper is reduced as it loses oxygen
• What are the key concepts of oxidation and reduction in metal reactions?

  • Oxidation: Gain of oxygen
  • Reduction: Loss of oxygen
  • Example: Magnesium oxidized, Copper reduced
