Answer 1

To balance the equation \( \text{CH}_4 + \_\_\_\_ \text{Cl}_2 \rightarrow \text{CCl}_4 + \_\_\_\_ \text{HCl} \), we first identify the number of each type of atom on both sides of the equation.

On the left side:
- Carbon (C): 1 (from CH₄)
- Hydrogen (H): 4 (from CH₄)
- Chlorine (Cl): 2 (from Cl₂)

On the right side:
- Carbon (C): 1 (from CCl₄)
- Hydrogen (H): 1 (from HCl)
- Chlorine (Cl): 4 (from CCl₄) + 1 (from HCl) = 5

To balance it, we can trial and error with the provided options.

### Testing the options:
1. **Option (4, 4)**:
- 4 CH₄ + 4 Cl₂ → 4 CCl₄ + 4 HCl
- Left: C = 4, H = 16, Cl = 8
- Right: C = 4, H = 4, Cl = 16
- **Not balanced.**

2. **Option (3, 2)**:
- 3 CH₄ + 2 Cl₂ → 3 CCl₄ + 2 HCl
- Left: C = 3, H = 12, Cl = 4
- Right: C = 3, H = 2, Cl = 14
- **Not balanced.**

3. **Option (2, 4)**:
- 2 CH₄ + 4 Cl₂ → 2 CCl₄ + 4 HCl
- Left: C = 2, H = 8, Cl = 8
- Right: C = 2, H = 4, Cl = 8
- **Not balanced.**

4. **Option (1, 2)**:
- 1 CH₄ + 2 Cl₂ → 1 CCl₄ + 2 HCl
- Left: C = 1, H = 4, Cl = 4
- Right: C = 1, H = 2, Cl = 6
- **Not balanced.**

### Correct Balancing:
Let's try balancing it directly to find if a straightforward approach shows us the answer:
To balance:

1. **Chlorine**: CCl₄ has 4 Cl, so we need 2 Cl₂ (since each Cl₂ gives 2 Cl).
2. **Hydrogen**: We will need 4 HCl for 4 H.

Final Balanced Equation:
- Therefore, 1 CH₄ + 2 Cl₂ → 1 CCl₄ + 4 HCl.

Looks like I miscomputed previously; reviewing the equation, we notice:

The numbers that balance the original equation accurately are:

- **1, 4** for CH₄ & HCl respectively.

Thus the correct answer isn't listed explicitly among your options, however **1** and **4** would be the correct combination to balance if they were present.

If I strictly follow provided pairs, it's evident that:
**The balanced answer set (1, 4)** isn't present in the multiple choice responses, further correcting confirms an error in logical extrapolation from provided or implied conditions.
Thus:
**Reviewing acceptable responses lists significant errors, check reevaluation of setup or probable amendments for clarity adjustments; choice exempts and correct predictors align.**
