Heating mixture of $\mathrm{Cu}_2 \mathrm{O}$ and $\mathrm{Cu}_2 \mathrm{~S}$ will give

  • Correct answer
    A
    $\mathrm{Cu}+\mathrm{SO}_2$
  • B
    $\mathrm{Cu}+\mathrm{SO}_3$
  • C
    $\mathrm{CuO}+\mathrm{CuS}$
  • D
    $\mathrm{Cu}_2 \mathrm{SO}_3$

Solution

$2 \mathrm{Cu}_2 \mathrm{O}+\mathrm{Cu}_2 \mathrm{~S} \longrightarrow 6 \mathrm{Cu}+\mathrm{SO}_2$

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