Reactivity Series Of Metals Flashcards
1
Q
- What are metals extracted from?
A
- Most metals are extracted from their ore.
2
Q
- What is an ore?
A
- An ore is a mineral found in the earths crust that contains metal compounds.
3
Q
- How are the metals extracted from their ores?
A
- The method used to extract a metal from its ore depends on the stability and reactivity of the metal.
4
Q
- How are very reactive metals such as aluminium extracted from their ore?
A
- Very reactive metals are extracted from their ore through electrolysis.
5
Q
- How are the less reactive metals extracted?
A
- Less reactive metals are extracted through reduction or displacement.
6
Q
- What is electrolysis?
A
- Electrolysis is the process in which ionic substances are decomposed.
- Electrolysis is very expensive and require a lot of energy.
7
Q
- What is a displacement reaction of metal oxides?
A
- In a reactivity series you are competing for the compound so the more reactive a metal is it will displace a less reactive metal from its compound.
