Hi, I've been working on this problem for some time now but absolutely cannot figure out the part two section to this. I'd love some help, thanks!
![## Redox Reactions
### Identification of Half-Reactions
**(1) Identify each of the following half-reactions as either an oxidation half-reaction or a reduction half-reaction.**
| Half-reaction | Identification |
|---------------------------------|----------------|
| Cr(s) → Cr³⁺(aq) + 3e⁻ | Oxidation |
| Cd²⁺(aq) + 2e⁻ → Cd(s) | Reduction |
### Writing Balanced Equations
**(2) Write a balanced equation for the overall redox reaction. Use smallest possible integer coefficients.**
The section involves a visual representation to help balance the redox reaction, including the reactants and products:
- Two images depict reactants with labels `A₂` and `A⁰`.
- A reaction arrow pointing to the products follows.
- Two images depict products with labels `A₂` and `A²⁰`.
To support the visual balance:
- The first reactant image shows `A₂` in a box.
- The second reactant image shows `A²` in a box.
- The first product image shows `A₂` in a box.
- The second product image shows `A²` in a box.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2be65d23-e07e-4ce3-8dd7-b7173547e175%2F4c21b1d6-010a-418b-97c0-a16a5d2d0979%2Fyde9gjd_processed.png&w=3840&q=75)
