Question

Heating mixture of C u subscript 2 end subscript O and C u subscript 2 end subscript S will give

  1. C u plus S O subscript 2 end subscript  
  2. C u plus S O subscript 3 end subscript  
  3. C u O plus C u S  
  4. C u subscript 2 end subscript S O subscript 3 end subscript  

The correct answer is: C u plus S O subscript 2 end subscript


    C u subscript 2 end subscript S plus 2 C u subscript 2 end subscript O rightwards arrow 6 C u plus S O subscript 2 end subscript (Auto-reduction).
    This reaction occurs in reverberatory furnace to get metallic copper.
