To balance the equation \( \text{Fe} + \text{Cl}_2 \rightarrow \text{FeCl}_3 \) according to the law of conservation of mass, we need to ensure that the number of atoms of each element is the same on both sides.
Let's analyze the equation:
- On the left, we have:
- Iron (Fe): 1 atom
- Chlorine (Cl): 2 atoms (from Cl2)
- On the right, we have:
- Iron (Fe): 1 atom
- Chlorine (Cl): 3 atoms (from FeCl3)
To balance, we can adjust the coefficients:
1. We begin with the chlorines. Since we have 2 Cl atoms on the reactants side and 3 on the products side, we'll need to find the least common multiple of 2 and 3, which is 6.
2. To achieve 6 Cl on both sides:
- Place a coefficient of 3 in front of FeCl3 (3 * 2 = 6 Cl on the product side).
- This means we need 3 iron atoms, so we'll place a coefficient of 3 in front of Fe (3 Fe will also provide 3 Fe on the product side).
- To get 6 chlorine atoms from Cl2, we need a coefficient of 3 on Cl2 (3 Cl2 = 6 Cl).
The balanced equation becomes:
\[ 3 \text{Fe} + 3 \text{Cl}_2 \rightarrow 2 \text{FeCl}_3 \]
Thus, the correct coefficients from left to right for the balanced equation are **3, 3, 2**.
However, since this combination is not listed in your provided options, upon reevaluating:
The closest representation based on your choices that would correctly adjust the original equation while keeping balance would lead to this option not being represented accurately in coefficients, suggesting a misunderstanding or incorrect initial coefficients in the options offered.
### Based on the correct calculation, none seem to match. But checking through coefficients, the option **2, 3, 2** does reflect a form indicating closest adjustment has been made.
If forced to respond according to your listed options only, **2, 3, 2** reflects the necessary larger framework of parts to match closely although initially needing review as outlined.
Hence, the coefficients would best show as **3, 3, 2** for 3 Fe, 3 Cl2, 2 FeCl3 alone without given alternatives fitting.
