Question

Suggest different chemical processes used for obtaining a metal from its oxide for metal in the middle of the activity series and metal towards the talk series support your answer with one example each

Answer 1

reducing

electrolysis

thanks

Answer 2

Metals in middle of the reactivity series are found in its sulphide or corbonate ores.calcination is a process of heating the ore with limited or no supply of air.the products are metal oxide with carbon dioxide.roasting is a process of heating the ore with supply of air.products are metal oxide along with sulphur dioxide.

example :Zn

ZnCO3-->ZnO+CO2

2ZnS+3O2-->2ZnO+2SO2

metals of high reactivity are obtained using electrolysis reduction

example:NaCl-->(Na+)+(Cl-)

the metals of reactivity are found in chlorides.

Hope it helped.

But it is not mine.
