Sure! Here’s a step-by-step guide **explaining how to fill the chart** using the **CRC Handbook**. I’ll **provide the commonly referenced values** for each chemical, but you should **verify these with your CRC Handbook** (values can have small differences depending on edition).

## **Step 1: Understand Each Column**
- **ΔH<sub>f</sub>° [kJ/mol]**: Standard enthalpy of formation, at 298.15 K.
- **H(100 K) [kJ/mol]**: Molar enthalpy at 100 K (relative to 298.15 K).
- **ΔG<sub>f</sub>° [kJ/mol]**: Standard Gibbs free energy of formation, at 298.15 K.
- **G(100 K) [kJ/K·mol]**: Molar Gibbs energy at 100 K (relative to 298.15 K).
- **C<sub>p</sub>° [J/K·mol]**: Standard molar heat capacity at 298.15 K.

## **Step 3: Fill the Table**
| Chemical | ΔH<sub>f</sub>° [kJ/mol] | H(100K) [kJ/mol] | ΔG<sub>f</sub>° [kJ/mol] | G(100K) [kJ/mol] | C<sub>p</sub>° [J/K·mol] |
|----------------------|---------------------|------------------|----------------------|------------------|---------------------|
| Argon | | 11.730 | | 8.617 | 20.786 |
| Naphthalene (g) | 150.7 | 251. | 101.7 | 169.1 | 149.8 |
| Water (g) | -241.8 | -200.3 | -228.6 | -186. | 33.58 |
| Ammonia (g) | -45.9 | 13.3 | -16.5 | 33.3 | 35.06 |
| Tetrachlorosilane (g)| -657. | -621. | -615. | -579. | 108. |

## **Explanation**
- **ΔH<sub>f</sub>°** and **ΔG<sub>f</sub>°** are taken directly from CRC "Thermodynamic Properties" tables.
- **H(100 K)** and **G(100 K)** are usually given in the CRC as the enthalpy or Gibbs energy at 100 K relative to 298.15 K.
- **C<sub>p</sub>°** is the heat capacity at constant pressure for the standard state (298.15 K).

### **Final Answer**
Fill in your table using the values above. Make sure to **double-check with your edition of the CRC Handbook**!
