What are x , y and z respectively in the following reaction? aligned & xFe ²⁺( aq )+ yH ⁺( aq )+ zCr ₂ O ₇²⁻( aq ) y 2 H ₂ O ( l ) & + xFe ³⁺( aq )+2 zCr ³⁺( aq ) aligned

Options

  1. A14,1,6
  2. B14,6,1
  3. C6,1,14
  4. D6,14,1

Correct answer

D. 6,14,1

Step-by-step solution

The balanced chemical equation is :- aligned & 6 Fe ²⁺ (aq.) +14 H ⁺ (aq.) + Cr ₂ O ₇²⁻ (aq.) & 7 H ₂ O (l) +6 Fe ³⁺ (aq.) +2 Cr ³⁺ (aq.) aligned Thus, x=6, y=14 and z=1
