Write electrochemical cell notation. Write the cell notation for an electrochemical cell consisting of an anode where Zn(s) is oxidized to Zn²+ (aq) and a cathode where H+ (aq) is reduced to H₂(g) at a platinum electrode. Assume all aqueous solutions have a concentration of 1 mol/L and gases have a pressure of 1 bar.

**Electrochemical Cell Notation**

**Task:** Write the electrochemical cell notation for an electrochemical cell consisting of:

- An anode where \( \text{Zn(s)} \) is oxidized to \( \text{Zn}^{2+}(\text{aq}) \).
- A cathode where \( \text{H}^{+}(\text{aq}) \) is reduced to \( \text{H}_{2}(\text{g}) \) at a platinum electrode.

**Conditions:** Assume all aqueous solutions have a concentration of 1 mol/L and gases have a pressure of 1 bar.

**Balancing Redox Reactions**

**Reaction:**
I<sup>-</sup>(aq) + Rh<sup>+</sup>(aq) → I<sub>2</sub>(s) + Rh(s)

---

**(a)** To show your method, write the balanced half-reactions below. Use the smallest integer coefficients possible and show electrons as e<sup>-</sup>. If a box is not needed, leave it blank. (Coefficients of 1 are not needed).

**Oxidation half-reaction:**

[Box] + [Box] → [Box] + [Box]

**Reduction half-reaction:**

[Box] + [Box] → [Box] + [Box]

---

**(b)** To show your balanced equation, enter an integer in each of the boxes. If the integer is "1," do enter it even though you would normally not show that in the equation. Use the smallest integer coefficients possible.

[Box] I<sup>-</sup>(aq) + [Box] Rh<sup>+</sup>(aq) → [Box] I<sub>2</sub>(s) + [Box] Rh(s)

---

**Note:** Insert the appropriate coefficients in the boxes once you have balanced the reaction.
