Question

Two ores A and B were taken. On heating, ore A gives CO₂, whereas ore B gives SO₂. What steps will you take to convert them into metals?

Answer 1

Since the ore 'A' of the metal gives CO₂ upon heating, it is some metal carbonate (MCO₃). 

It can be converted to the metallic form as follows :

Since the ore 'Y' of the metal gives SO₂ upon heating, it can be some metal sulphide (MS). It can be converted to the metallic form as follows :
