Among following compounds, the number of those present in copper matte is ___________.
A. $\mathrm{CuCO_{3}}$
B. $\mathrm{Cu_{2}S}$
C. $\mathrm{Cu_{2}O}$
D. $\mathrm{FeO}$
Answer (integer)
1
Solution
<p>Copper matte is a mixture of copper sulfide and iron sulfide formed as a result of smelting of copper ore. It contains mainly copper sulfide (Cu<sub>2</sub>S) as the major component and iron sulfide (FeS) as a minor component.</p>
<p>
The compounds A. CuCO<sub>3</sub>, C. Cu<sub>2</sub>O, and D. FeO are not present in copper matte, but can be formed as a result of further processing or refining of the matte.</p>
<p>Therefore, among the given compounds, only "B. Cu<sub>2</sub>S" is present in copper matte.</p>
