### Exercise: Predicting Enthalpy Differences

**Objective:** Without referring to tables, predict which of the following has the higher enthalpy in each case.

**Instructions:** Drag the terms on the left to the appropriate blanks on the right to complete the sentences.

**Options:**

- 1 mol CO₂(s)
- 1 mol CO₂(g)
- 2 mol of hydrogen atoms
- 1 mol of H₂
- 1 mol H₂(g) and 0.5 mol O₂(g) at 25 °C
- 1 mol H₂O(g) at 25 °C
- 1 mol N₂(g) at 100 °C
- 1 mol N₂(g) at 300 °C

**Sentences:**

1. When comparing **1 mol CO₂(s)** or **1 mol CO₂(g)** at the same temperature, the one with the higher enthalpy is **[Blank]**.

2. When comparing **2 mol of hydrogen atoms** or **1 mol of H₂**, the one with the higher enthalpy is **[Blank]**.

3. When comparing **1 mol H₂(g) and 0.5 mol O₂(g) at 25 °C** or **1 mol H₂O(g) at 25 °C**, the one with the higher enthalpy is **[Blank]**.

4. When comparing **1 mol N₂(g) at 100 °C** or **1 mol N₂(g) at 300 °C**, the one with the higher enthalpy is **[Blank]**.
