Flashcards in The Reactivity Series Deck (5):
1

How can a metal be extracted from its ore chemically?

By reduction using carbon

2

What happens when a ore is reduced?

Oxygen is removed from it
Eg, Iron (III) Oxide + Carbon -> Iron + Carbon dioxide

3

What do metals HIGHER than carbon in the reactivity series have to be extracted by? What's a disadvantage?

Electrolysis - expensive

4

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.

In what is iron oxide reduced?

A blast furnace
