Need help with completing the table

Answer 1

To find the enthalpy change for the given reaction CCI (1) + S₂Cl₂(1) →
`CS_2`(g) +
`3Cl_2`(g), we can use the enthalpy change of the known reaction
`CS_2`(g) +
`3Cl_2`(g) → CCI (1) + S₂CI₂ (1). By following the steps of adding the equations and using the enthalpy change values, we can determine that the enthalpy change for the unknown reaction is approximately -608 kJ.

To find the enthalpy change for the given reaction CCI (1) + S₂Cl₂(1) →
`CS_2`(g) +
`3Cl_2`(g), we can use the enthalpy change of the known reaction
`CS_2`(g) +
`3Cl_2`(g) → CCI (1) + S₂CI₂ (1). Given that the enthalpy change of the known reaction is -304 kJ, we can use the fact that enthalpy change is a state function to find the enthalpy change for the unknown reaction.

1. Add the two equations together to cancel out the
   `CS_2`(g) and CCI (1) terms.
2. Use the enthalpy change values for the known reactions to calculate the enthalpy change for the unknown reaction.
3. Round the calculated value to the nearest kJ.

By following these steps, the enthalpy change for the reaction CCI (1) + S₂Cl₂(1) →
`CS_2`(g) +
`3Cl_2`(g) is approximately -608 kJ.
