Flashcards in The Reactivity Series Deck (5):
How can a metal be extracted from its ore chemically?
By reduction using carbon
What happens when a ore is reduced?
Oxygen is removed from it
Eg, Iron (III) Oxide + Carbon -> Iron + Carbon dioxide
What do metals HIGHER than carbon in the reactivity series have to be extracted by? What's a disadvantage?
Electrolysis - expensive
Metals [ ] carbon in the reactivity series can be extracted by reduction using carbon. This is because carbon can only take the [ ] away from metals which are [ ] reactive than carbon.
