For the Lewis structure of C2O42-, are the C --> O bonds the same strengths or different strengths?

I calculated the bond strength as being 7/5 or 1.4, all the same, but not sure.

 

The image depicts the Lewis structure of the oxalate ion (C₂O₄²⁻). 

### Structure Explanation:
- **Atoms**: The ion consists of two carbon atoms (C) double-bonded to two oxygen atoms (O) and single-bonded to the other two oxygen atoms.
- **Bonds**: 
  - Each carbon is double-bonded to one oxygen atom.
  - Each carbon is single-bonded to one additional oxygen atom that carries a negative charge.
- **Lone Pairs**:
  - Each oxygen atom has pairs of dots representing lone pairs of electrons.
  - Each single-bonded oxygen atom has three lone pairs.
  - Each double-bonded oxygen atom has two lone pairs.
- **Overall Charge**: The entire structure is enclosed in brackets with a 2- charge indicating that the oxalate ion carries a negative two charge.

### Significance:
Oxalate ions are commonly found in various salts and are critical in several biological processes and industrial applications. This structure helps in understanding the electronic distribution and reactivity of the oxalate ion.
