![**Redox Reaction: Ethylene Combustion**
In this section, we analyze the redox reaction of the combustion of ethylene (C₂H₄). The balanced chemical equation is:
\[ \text{C}_2\text{H}_4(g) + 3 \text{O}_2(g) \rightarrow 2 \text{CO}_2(g) + 2 \text{H}_2\text{O}(g) \]
**Oxidation States (OS) Analysis:**
| Element | Initial OS | Final OS |
| ------- | ---------- | -------- |
| C | | |
| H | | |
| O | | |
**Agents Identification:**
- **Oxidizing Agent:**
- Selected: C₂H₄
- Options: C₂H₄, O₂
- **Reducing Agent:**
- Selected: O₂
- Options: C₂H₄, O₂
**Explanation:**
- **Oxidizing Agent:** The species that gets reduced by gaining electrons during the reaction. In this setup, oxygen (O₂) is typically the oxidizing agent.
- **Reducing Agent:** The species that gets oxidized by losing electrons. Ethylene (C₂H₄) is typically the reducing agent in this reaction.
**Note:** The oxidation states need to be determined to understand the transfer of electrons and complete the table. This involves assigning the appropriate values based on standard rules for calculating oxidation states.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd62f153a-5fff-4ab2-99fd-0b9d33305ca9%2F9288c2b1-3a02-4cf0-9837-5d08993904f3%2F8ispz0h_processed.jpeg&w=3840&q=75)
