Vedclass · Answer

(B) Roasting is a metallurgical process in which a sulfide ore is heated strongly in the presence of excess air to convert it into its oxide form.In the reaction $2ZnS_{(s)} + 3O_{2(g)} \xrightarrow{\Delta} 2ZnO_{(s)} + 2SO_{2(g)}$,zinc sulfide $(ZnS)$ is heated in the presence of oxygen to form zinc oxide $(ZnO)$ and sulfur dioxide $(SO_2)$.Therefore,this reaction represents roasting.Option $A$ represents calcination (heating carbonate ore in limited air).Option $C$ represents reduction of metal oxide using carbon.Option $D$ represents the reaction of metal with steam.

Which of the following reactions is called roasting?
