Among following compounds, the number of those present in copper matte is

____

.
A.

CuCO_{3}

Cu_{2} S

Cu_{2} O

D. FeO

Answer: 1

Solution

Copper matte is the molten mixture obtained after smelting the roasted ore and consists essentially of cuprous sulphide and ferrous sulphide,

C u_{2} S

and

FeS

. Of the compounds listed, the carbonate belongs to the ore, cuprous oxide is formed later during bessemerisation, and iron is present in the matte as its sulphide rather than its oxide. Only cuprous sulphide is a constituent of copper matte, so the number present is one.
