`2C + ("limited")O_(2) to`…………..

Answer

To solve the question "2C + (limited) O₂ to ...", we need to determine the product formed when carbon reacts with a limited amount of oxygen.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants are 2 carbon atoms (2C) and a limited amount of oxygen (O₂).

2. **Understand the Reaction Conditions**:
- The question specifies that oxygen is limited. This means that there is not enough oxygen available for complete combustion of carbon.

3. **Determine the Product**:
- When carbon reacts with a limited supply of oxygen, it forms carbon monoxide (CO). This is because there isn’t enough oxygen to convert all the carbon into carbon dioxide (CO₂).

4. **Write the Reaction**:
- The balanced chemical equation for this reaction is:
\[ 2C + O₂ \rightarrow 2CO \]
- Here, 2 moles of carbon react with 1 mole of oxygen to produce 2 moles of carbon monoxide.

5. **Check if the Equation is Balanced**:
- On the left side, we have 2 carbon atoms and 2 oxygen atoms (from O₂).
- On the right side, we have 2 carbon atoms (from 2CO) and 2 oxygen atoms (from 2CO).
- Therefore, the equation is balanced.

6. **Conclusion**:
- The product formed when 2 carbon atoms react with a limited amount of oxygen is carbon monoxide (CO).

### Final Answer:
2C + (limited) O₂ → 2CO
