Carbon and Hydrogen are often added to the reactivity series for comparison. |
|
Which two non-metal elements are often added to the reactivity series? Show old chem data sheet and ask which two are the odd ones out. They are in italics and they are identified as non-metals.
Complete the card sort of reactivity series using the reactivity fact sheet |

|
|
Metals more reactive than hydrogen will react with water as they will displace the hydrogen forming metal oxides. |
|
Why don't we find pure metals that are more reactive than hydrogen in the ground? |
|
|
|
The rocks that have significant amounts of metal oxides in are known as ores. |
|
What do we call rocks that have significant amounts of metal compounds in? |
|
|
|
In order to obtain useable metal it needs to be chemically separated from the oxygen. |
|
What needs to be done to get useable metals? |
|
|
|
The blast furnace is used to obtaining some metals from metal oxides using carbon.
eg Iron from iron oxide. |
|
What type of furnace is used to produce iron? Extracting metal on a match head: http://www.rsc.org/learn-chemistry/resource/res00000722/extraction-of-iron-on-a-match-head?cmpid=CMP00005113 |
|
|
|
Carbon is more reactive than iron so the carbon displaces the iron to form carbon dioxide leaving the iron by itself. |
|
What is added to to the furnace to remove the oxygen from the ore? |
|
|
| A |
Carbon can only displace metals that are less reactive than itself. |
|
What determines if carbon can displace the metal? Using reactivity series student to predict which metals are obtained using carbon. |
