Answer 1

Answer:(i) The metal is zinc (Zn). (ii) The carbonate ore is first heated strongly in limited supply of oxygen and changed into its oxide. This process is called calcination.  ZnCO3(s) +Heat----->ZnO(s) +CO2(g) Zinc oxide is then reduced to zinc metal by heating it with carbon. This process is called reduction.  ZnO(s) + C(s) +Heat ---->   Zn(s) + CO(g)
