Q

How can a metal be extracted from its ore chemically?

A

By reduction using carbon

2
Q

What happens when a ore is reduced?

A

Oxygen is removed from it

Eg, Iron (III) Oxide + Carbon -> Iron + Carbon dioxide

3
Q

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

A

Electrolysis - expensive

4
Q

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.

A

below
oxygen
less

5
Q

In what is iron oxide reduced?

A

A blast furnace
