## Chemical Reaction and Classification of Reactants and Products

### Reaction Equation:
\[ \text{CH}_4(g) + \text{H}_2\text{O}(g) + \text{energy} \rightarrow 3\text{H}_2(g) + \text{CO}(g) \]

### Identifying Reactants and Products:
- **H\(_2\)O(g)** - Reactant
- **CH\(_4\)(g)** - Reactant
- **H\(_2\)(g)** - Product
- **CO(g)** - Product

### Energy Changes in the Reaction:
When the reaction takes place, energy is **absorbed**.

### Nature of the Reaction:
The reaction is **endothermic**.

**Explanation:**
- **Reactants:** Substances that are consumed during the reaction (H\(_2\)O and CH\(_4\)).
- **Products:** Substances that are formed as a result of the reaction (H\(_2\) and CO).
- **Endothermic Reaction:** The reaction requires energy input (energy is absorbed) for it to proceed.

In the following equation for a chemical reaction, the notation (s), (l), or (g) indicates whether the substance indicated is in the solid, liquid, or gaseous state.

\[ 2NO(g) + 2H_2(g) \rightarrow N_2(g) + 2H_2O(l) + \text{energy} \]

Identify each of the following as a product or a reactant:

- \( H_2(g) \) **reactant**
- \( NO(g) \) **reactant**
- \( N_2(g) \) **product**
- \( H_2O(l) \) **product**

When the reaction takes place energy is **released**.

The reaction is **exothermic**.
