**Oxidation-Reduction Reactions Identification**

In this exercise, you need to determine whether each chemical reaction listed in the table below is an oxidation-reduction (redox) reaction. If the reaction qualifies as a redox reaction, you need to identify both the reducing agent and the oxidizing agent by writing down their respective chemical formulas.

1. **Reaction 1:**
   \[
   2Cl_2 (g) + Sn (s) \rightarrow SnCl_4 (s)
   \]
   - Redox reaction? : \(\bigcirc\) Yes  \(\square\) No
   - Reducing agent: \(\square\)
   - Oxidizing agent: \(\square\)

2. **Reaction 2:**
   \[
   7O_2 (g) + 2CH_3CH_3 (g) \rightarrow 4CO_2 (g) + 6H_2O (g)
   \]
   - Redox reaction? : \(\bigcirc\) Yes  \(\square\) No
   - Reducing agent: \(\square\)
   - Oxidizing agent: \(\square\)

3. **Reaction 3:**
   \[
   3Cr(NO_3)_2 (aq) + 2Al (s) \rightarrow 3Cr (s) + 2Al(NO_3)_3 (aq)
   \]
   - Redox reaction? : \(\bigcirc\) Yes  \(\square\) No
   - Reducing agent: \(\square\)
   - Oxidizing agent: \(\square\)

For each reaction, determine if the change in oxidation states of the reactants qualifies the reaction as a redox reaction. Then identify the substance that donates electrons (reducing agent) and the substance that accepts electrons (oxidizing agent).
