Key Questions:

1. Which two non-metal elements are often added to the reactivity series?
   • Carbon and Hydrogen are often be added to the reactivity series.
2. Why don't we find pure metals that are more reactive than hydrogen in the ground?
   • The metal displaces the hydrogen, found in ground water, to produce metal oxides.
3. What do we call rocks that have significant amounts of metal compounds in?
   • The rocks that have significant amounts of metal oxides in are known as ores.
4. What needs to be done to get useable metals?
   • Metal in metal oxides needs to be chemical separated from the oxygen.
5. What type of furnace is used to produce iron?
   • The blast furnace is used to produce Iron from iron oxide.
6. What is added to to the furnace to remove the oxygen from the ore?
   • Carbon is added to blast furnace remove the oxygen from the ore.
7. What determines if carbon can displace the metal?
   • Carbon can only displace metals that are less reactive than itself.
