Q44 / 116 · NTA Abhyas (NEET) 2020 · Chemistry · General Principles and Processes of Isolation of Metals

Heating mixture of Cu 2 O and Cu 2 S will give

  • Correct answer
    A
    Cu+SO 2
  • B
    Cu+SO 3
  • C
    CuO+CuS
  • D
    Cu 2 SO 3

Solution

Cu 2 S+2Cu 2 O→ 6Cu+SO 2 (Auto-reduction).
