Separating metals from metal oxides

Question 1

What is a reaction called that separates a metal from its oxide

Answer 1

A reduction reaction

Question 2

What is an ore

Answer 2

A type of rock that contains metal compounds

Question 3

Some metals can be extracted by reduction with

Answer 3

Carbon

Question 4

How are metals separated from their oxides

Answer 4

1. Metals are oxidised to make metal oxides
   —>oxidation
2. The metal oxide is them reduce to the metal
   —>recuction

Question 5

How are metals extracted from their ores using carbon

Answer 5

-by reduction using carbon
-the ore is reduces as oxygen is removed from it and carbon gains oxygen so is oxidised
-the position of the metal in the reactivity series determines why here it can be extracted using carbon

Question 6

What do metals higher than carbon in the reactivity series have to be extracted by

Answer 6

Electrolysis

Question 7

What do metals below carbon in the reactivity series have to be extracted by

Answer 7

Reduction using carbon
