![### Formation of Magnesium Oxide from Magnesium and Oxygen
The chemical reaction for the formation of magnesium oxide is given by:
\[ 2\text{Mg}(\text{s}) + \text{O}_2(\text{g}) \rightarrow 2\text{MgO}(\text{s}) \]
#### Thermodynamic Data Table
This data is used to calculate the changes in entropy and enthalpy for the surroundings, system, and total reaction.
| State and Substance | \(\Delta H^\circ_f \) (kJ/mol) | \( S^\circ \) [J/(K·mol)] |
|---------------------|-----------------|--------------------|
| \(\text{PCl}_3\)(g) | -287.0 | 311.7 |
| \(\text{PCl}_5\)(g) | -374.9 | 364.5 |

### Explanation
- **\(\Delta H^\circ_f\)**: Standard enthalpy of formation in kilojoules per mole (kJ/mol).
- **\(S^\circ\)**: Standard molar entropy in joules per Kelvin per mole \([J/(K·mol)]\).
This table includes values for several substances, including \(\text{MgO}\), which is crucial for calculations related to this exothermic reaction. The enthalpy of formation (\(\Delta H^\circ_f\)) and entropy (\(S^\circ\)) for each substance will assist in determining the thermodynamic properties of the reaction.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff85a7368-ad51-49a6-b8f6-6f50d27fc24a%2Fe6947755-0b52-429d-8c19-bcc37eb7a025%2Fs22kyxg_processed.png&w=3840&q=75)
