Which metals are extracted by heating their oxides?
Metals of group I in reactivity series
Metals of group II in reactivity series
Metals below Carbon in reactivity series.
None of the choices
Metals below Carbon in the reactivity series can be extracted by heating the oxide with Carbon or Carbon monoxide.
Which metals are extracted by electrolysis and cannot be reduced by CO2 or CO ?
How are the less reactive metals (which are quite low in the reactivity series) extracted? Explain with the help of an example.
