For the balanced redox equation X MnO4⁻ + Y C2O4²⁻ + Z H⁺ → X Mn²⁺ + 2Y CO2 + Z/2 H2O, what are the values of X, Y, and Z, respectively?

1. 2, 5, 16
2. 8, 2, 5
3. 3, 1, 6
4. 5, 8, 4

Correct answer: 3, 1, 6

Solution

The correct values of X, Y, and Z are determined by balancing the number of atoms and charges on both sides of the equation. In this case, 3 MnO4⁻ ions reduce to 3 Mn²⁺ ions, 1 C2O4²⁻ ion produces 2 CO2 molecules, and 6 H⁺ ions balance the hydrogen and oxygen atoms, leading to the balanced equation.
