Using the concept of oxidation number, identify the substances undergoing oxidaton and reduction in the following reactions.
`C+O_(2)toCO_(2)`

Explanation

To identify the substances undergoing oxidation and reduction in the reaction \( C + O_2 \rightarrow CO_2 \) using the concept of oxidation numbers, we can follow these steps:

### Step 1: Assign Oxidation Numbers
- In the reactants:
- Carbon (C) is in its elemental form, so its oxidation number is **0**.
- Oxygen (O) in \( O_2 \) is also in its elemental form, so its oxidation number is **0**.

- In the products:
...
