2) 2
3) 3
4) 4

Answer 1

To balance the reaction CS2 + Cl2 → CCl4 + S2Cl2, we follow systematic steps, ending with a balanced equation: 1CS2 + 3Cl2 → 1CCl4 + 2S2Cl2. The correct coefficients are 1, 3, 1, 2 respectively.

Step-by-step explanation:

To balance the chemical equation provided, we'll follow a series of steps to ensure that the number of atoms of each element is equal on both sides of the reaction. The chemical reaction that needs balancing is CS2 + Cl2 → CCl4 + S2Cl2.

Steps in Balancing a Chemical Equation:

1. Identify the most complex substance.
2. Adjust coefficients to obtain the same number of atoms of elements that appear in only one reactant and one product, if possible.
3. Balance polyatomic ions as a unit if they are present on both sides of the equation.
4. Balance the remaining atoms.
5. Count the number of atoms of each kind on both sides to ensure the equation is balanced.

Applying these steps, we start by balancing elements that appear in only one reactant and one product. Next, polyatomic ions would be balanced if present. Finally, the remaining atoms are balanced, and we confirm by counting the atoms.

The balanced equation would be:
1CS2 + 3Cl2 → 1CCl4 + 2S2Cl2

Using this procedure, the proper coefficients to balance the reaction given are: 1, 3, 1, 2.
