articles. Identify the metal X. How will you convert this sulphide ore into the metal?
Explain with equations.​

Answer 1

Answer:

Metal X is Zinc.

Explanation:

It is found as its sulphide ore (ZnS).

To convert it from its sulphide ore to pure metal, the first step is roasting (excess air) and the second step is reduction to metal.

Following are the reactions:-

• First step,

2ZnS+3O2 ----->2ZnO+2SO2.

• Second step,

2ZnO+C ------> 2Zn+CO2.
