New cards

how is a metal ore formed?

  • oxidation

    • gain of oxygen

2
New cards

what is a reaction separating the metal from its oxide called?

  • reduction reaction

    • loss of oxygen

3
New cards

how are metals higher than carbon on the reactivity series extracted?

electrolysis (expensive)

4
New cards

how can metals below carbon in the reactivity series be extracted?

  • reduction using carbon

    • can only take oxygen from metals less reactive than itself

5
New cards

how can metals below carbon on the reactivity series be extracted by reduction with carbon?

  • oxygen removed from ore

  • carbon gains oxygen
