Reaction of Metals with Oxygen

• What do metals form when they react with oxygen?

  Metal oxides
• What is the significance of oxidation in the reaction of metals with oxygen?

  It indicates that the metal has gained oxygen.
• How would you describe the reaction of magnesium with oxygen?

  It is a vigorous reaction that forms magnesium oxide.
• How does the reaction rate of iron with oxygen compare to that of magnesium?

  Iron reacts more slowly than magnesium.
• What happens during the oxidation of a metal?

  • The metal gains oxygen
  • The metal is transformed into a metal oxide
• 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 does it mean for a metal to be oxidized?

  It means the metal has gained oxygen.
• What is the process of reduction in terms of metal reactions?

  • It involves the loss of oxygen from a metal compound
  • The metal is transformed back into its elemental form
• In the reaction of magnesium oxide, what happens to the magnesium?

  Magnesium is reduced as it loses oxygen.
• In the reaction of calcium with copper oxide, which element is oxidized and which is reduced?

  Calcium is oxidized and copper is reduced.
• What are the key concepts of oxidation and reduction in metal reactions?

  • Oxidation: Gain of oxygen
  • Reduction: Loss of oxygen
  • Formation of metal oxides
• What is the main outcome when metals react with oxygen?

  Formation of metal oxides
