Question

Aluminium cannot be extracted from its ore by heating with carbon. Think about the reactivity of metals and suggest a reason for this.

Answer 1

Answer:

We can see from the table that reactive metals, such as aluminium, are extracted by electrolysis , while a less reactive metal, such as iron, may be extracted by reduction with carbon. Because gold it is so unreactive, it is found as the native metal and not as a compound. It does not need to be chemically separated.
