Read the following question and answer:
 
A metal X is obtained from its sulphide ore Y by heating it strongly in the presence of air. During heating, the ore first forms an oxide, which on further heating decomposes to give the metal in liquid form.

i. Identify the metal X.
ii. Name the ore Y.
iii. Write the balanced chemical equations involved in the extraction of X.
 
i. The metal X is
 
ii. The sulphide ore Y is
 
iii. The balanced chemical equations involved are:
