Extraction of metals and reduction Flashcards
What type of metals are found in the Earth as the metal itself?
Unreactive metals like gold.
How are most metals found in the Earth?
As compounds that require chemical reactions to extract the metal.
How can metals less reactive than carbon be extracted from their oxides?
By reduction with carbon.
What does reduction involve in the context of metal extraction?
The loss of oxygen.
What is the scope of knowledge and understanding in this context?
Limited to the reduction of oxides using carbon.
Is knowledge of specific extraction processes details required?
No, it’s not required.
What should students be able to do regarding metal extraction processes?
Interpret or evaluate specific metal extraction processes when given appropriate information.
In terms of oxygen gain or loss, what should students be able to identify?
The substances that are oxidized or reduced.
