|
How are metals extracted when they can’t be extracted using only heat? What is the general word equation for this? |
Carbon and heat is used
Metal Oxide + Carbon -> Metal + Carbon Dioxide |
|
|
How is iron extracted? |
Using a blast furnace. The oxygen must be removed from the iron oxide to leave the iron. |
|
|
What is electrolysis? |
A process which uses electricity to break up a compound. |
|
|
How does electrolysis work? |
The positively charged metal puns and the negatively charged metal ions can move freely. They carry the current and allow conduction. |

|
|
What is the order of reactivity? |
Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Copper |
|
|
What is an ore? |
A naturally occurring rock that contains metal and metal compounds in sufficient amounts to make it worthwhile extracting them |
|
|
What is an alloy? |
A mixture of metals used to give specific properties |
|
|
