Consider the following reaction 2 X S + 3 O 2 → Δ 2 X O + 2 S O 2 2XO+XS → Δ 3X+SO 2 The 'X' cannot be

Options

  1. AHg
  2. BPb
  3. CZn
  4. DCu

Correct answer

C. Zn

Step-by-step solution

Here X cannot be Zn as Zn is extracted from its sulphide ore by roasting followed by carbon reduction Hg, Pb and Cu are extracted by self reduction from their sulphide ores.
