Consider the following reaction xMn O _ 4 ^ - + y C _ 2 O _ 4 ^ 2 -...

Consider the following reaction

xMnO4−+yC2O42−+zH+→xMn2++2yCO2+z2H2OxMn{O}_{4}^{-} + y{C}_{2}{O}_{4}^{2 -} + z{H}^{+} \to xM{n}^{2 +} + 2yC{O}_{2} + \dfrac{z}{2}{H}_{2}O

The values of x, y and z in the reaction are, respectively

Options

  1. A5, 2 and 8
  2. B2, 5 and 8
  3. C2, 5 and 16
  4. D5, 2 and 16

Correct answer

C. 2, 5 and 16

Step-by-step solution

2MnO4−+5C2O42−+16H+→2Mn2++10CO2+8H2O2Mn{O}_{4}^{-} + 5{C}_{2}{O}_{4}^{2 -} + 16{H}^{+} \to 2M{n}^{2 +} + 10C{O}_{2} + 8{H}_{2}O

Here x = 2, y = 5 and z = 16.
