Question

what are two chemical processes used for obtaining a metal from its oxide? write the equation

Answer 1

The chemical process used for obtaining a metal from its oxide is reduction. In this process, metal oxides are reduced by using suitable reducing agents such as carbon or by highly reactive metals to displace the metals from their oxides.

The chemical process used for obtaining a metal from its oxide is reduction. In this process, metal oxides are reduced by using suitable reducing agents such as carbon or by highly reactive metals to displace the metals from their oxides.For example, zinc oxide is reduced to metallic zinc by heating with carbon.

ZnO(s) + C(s) -> Zn(s) + CO (g)

Manganese dioxide is reduced to manganese by treating it with aluminium powder. In this case, aluminium displaces manganese from its oxide.

3Mno2(s) + 4Al(s) -> 3Mn(l) + 2Al2O3(s) +Heat

Oxides of more reactive metals are reduced by electrolysis.

Answer 2

reduction process is the process which is used for obtaining a metal from its oxide
