Balance the following equation by ion electron method in the acidic medium.
`Cr_(2)O_(7)^(2-)+C_(2)O_(4)^(2-)+H^(+)toCr^(3+)+CO_(2)+H_(2)O`

Explanation

To balance the equation `Cr_(2)O_(7)^(2-) + C_(2)O_(4)^(2-) + H^(+) → Cr^(3+) + CO_(2) + H_(2)O` using the ion-electron method in acidic medium, we will follow these steps:

### Step 1: Identify Oxidation States
- Determine the oxidation states of each element in the reactants and products.
- In `Cr_(2)O_(7)^(2-)`, chromium (Cr) has an oxidation state of +6.
- In `C_(2)O_(4)^(2-)`, carbon (C) has an oxidation state of +3.
- In `Cr^(3+)`, chromium has an oxidation state of +3.
- In `CO_(2)`, carbon has an oxidation state of +4.
