|
|
Decribe the displacement that occurs in a thermite reaction involving iron oxide. |
Single displacement - aluminum and iron oxide and displaces iron out |
|
|
What product makes a thermite reaction useful? |
The liquid metal that is the result of the energy produced in a thermite reaction is useful. |
|
|
Explain how a thermite reaction can be used to produce pure copper. |
It will diplace copper out making pure liquid copper and aluminum oxide |

|
How are seashells used to help extract magnesium from seawater? |
Seashells are a source of calcium carbonate which can be decomposed to produce calcium oxide. This is used to extract magnesium in a displacement reaction |
|
|
During the extraction of magnesium from seawater, if it is converted into soluble magnesium chloride in the next step? |
The precipitation lets the magnesium to be easily seperated from other ions in seawater |
|
|
What is an advantage of the production of chlorine in the final step of extracting magnesium from seawater? |
Chlorine can be reused to make hydrochloric acid which is needed to neutralize. |
