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 ?
Statement 1: It is comparatively easier to extract the metals that are present at top of the reactivity series than the metals present at the bottom of the reactivity series. Statement 2: Metals at the top of the reactivity series are highly reactive in comparison with the metals at the bottom.
