State how activity series of metals playse a role in extraction of metals from their oxides.

The extraction of metals from sulphide ore involves

The extraction of metal from sulfide ore is done by

The important step in the extraction of metal from carbonate ore is

In the stages involved in the extraction of metals in general - give reasons for following Reduction of metallic oxides to metal in the extraction of metals from the ores - is based on the position of the metal in the activity series.

M'- is an element above Zn in the activity series of metals. State why conventional reducing agents cannot reduce the oxide of M to metal.

Extraction of metal from the ore cassiterite involves

Why should the metal sulphides and carbonates be converted to metal oxides in the process of extraction of metal from them?

In the activity series of metals-M is a metal above hydrogen in the activity series & its oxide has the formula M_(2)O when dissolved in water forms the corresponding hydroxide which is a good conductor of electricity State the no. of electrons in the outermost shell of M.
