**Question:**  
Which of the following are redox processes?

- [ ] \( \text{Cr}^{3+} \rightarrow \text{CrO}_4^{2-} \)

- [ ] \( \text{CO}_2 \rightarrow \text{CO}_3^{2-} \)

- [ ] \( \text{SO}_3 \rightarrow \text{SO}_4^{2-} \)

- [ ] \( \text{NO}_2^- \rightarrow \text{NO}_3^- \)

- [ ] \( \text{VO}_3 \rightarrow \text{VO}_2 \)

**Explanation:**

This list consists of potential chemical reactions or transformations. A redox (reduction-oxidation) process involves the change in oxidation states of atoms, typically involving a transfer of electrons, where one substance is oxidized and another is reduced.

Consider each reaction and ascertain whether a redox process is occurring by analyzing any change in oxidation states or electron transfer within each listed reaction.
