Q27 / 160 · AP EAMCET 2017 (26 Apr Shift 1) · Chemistry

Copper matte contains

  • A
    CuO, FeS
  • Correct answer
    B
    $\mathrm{Cu}_2 \mathrm{~S}, \mathrm{FeS}$
  • C
    $\mathrm{CuO}, \mathrm{Cu}_2 \mathrm{~S}$
  • D
    $\mathrm{Cu}_2 \mathrm{~S}, \mathrm{FeO}$

Solution

$\underset{\substack{\text { Copper pyrites } \\ \text { [ore] }}}{2 \mathrm{Cu} \mathrm{FeS}}{ }^{2 \mathrm{O}_2} \longrightarrow \underbrace{\mathrm{Cu}_2 \mathrm{~S}+2 \mathrm{FeS}}_{\text {Matter }}+\mathrm{SO}_2(\mathrm{~g})$

Hence, the correct answer is option: 'B'.
