Question

For the redox reaction,

$MnO_{4}^{-}$+ $C_{2}O_{4}^{2 -}$+ H⁺$\longrightarrow$Mn²⁺ + CO₂ + H₂ O

the correct coefficients of the reactants for the balanced reaction are respectively

$MnO_{4}^{-},C_{2}O_{4}^{-},H^{+}$:

• A. 2, 5, 16
• B. 16, 3, 12
• C. 15, 16, 12
• D. 2, 16, 5

Answer 1

Answer: (A)

2, 5, 16

Answer 2

$2Mn{O_{4}}^{-} + 5C_{2}{O_{4}}^{2 -} + 16H^{+} \rightarrow$

$2Mn^{2 +} + 10CO_{2} + 8H_{2}O$
