Question

what is the coefficient for h+ in the half reaction? h₂c₂o₄ → 2co₂ + ?h⁺

Explanation:

Step1: Analyze the number of H atoms on each side

On the left side, in \(H_2C_2O_4\), there are 2 H atoms. On the right side, the H atoms are in \(H^+\).

Step2: Balance the H atoms

To balance the H atoms, since there are 2 H atoms in \(H_2C_2O_4\), we need 2 \(H^+\) ions on the right side to have the same number of H atoms. So the coefficient for \(H^+\) should be 2.

Answer:

2
