1.	Suggest different chemical processes used for obtaining a metal from metal oxide for metals in the middle of the reactivity series and metals towards the top of the reactivity series. Support your answer with an example of each.
Answer» 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
