Question

Metal x is found in nature as its sulphide xs. It is used in the galvanisation of iron articles. Identify the metal x. How will you convert this sulphide ore into the metal? Explain with

Answer 1

Metal'x' is zinc

Converting sulphide ore into metal by the presence of excess air is called roasting.

So the equation is

2zns + 3o2 = 2zno + 2so2

Later zinc oxide is converted into zinc and carbon monoxide by adding carbon in presence of heat

Zno + c = zn + co
