![# Classifying Chemical Reactions
In this section, we will categorize the following chemical reactions based on their types: synthesis, decomposition, single exchange, or double exchange.
### Reaction Examples:
1. **Reaction 3:**
\[
\text{N}_2 \,(\text{g}) + 3\text{H}_2 \,(\text{g}) \rightarrow 2\text{NH}_3 \,(\text{g})
\]
- **Type:** Synthesis Reaction
- **Explanation:** Two or more reactants (\(\text{N}_2\) and \(\text{H}_2\)) combine to form a single product (\(\text{NH}_3\)).
2. **Reaction 4:**
\[
\text{C}_6\text{H}_{12}\text{O}_6 \,(\text{aq}) \rightarrow 2\text{C}_2\text{H}_6\text{O} \,(\text{aq}) + 2\text{CO}_2 \,(\text{g})
\]
- **Type:** Decomposition Reaction
- **Explanation:** A single compound (\(\text{C}_6\text{H}_{12}\text{O}_6\)) breaks down into simpler compounds (\(\text{C}_2\text{H}_6\text{O}\) and \(\text{CO}_2\)).
3. **Reaction 5:**
\[
\text{Ca} \,(\text{s}) + \text{Zn(NO}_3\text{)}_2 \,(\text{aq}) \rightarrow \text{Ca(NO}_3\text{)}_2 \,(\text{aq}) + \text{Zn} \,(\text{s})
\]
- **Type:** Single Exchange Reaction
- **Explanation:** The calcium (\(\text{Ca}\)) replaces zinc (\(\text{Zn}\)) in the compound \(\text{Zn(NO}_3\text{)}_2\), forming \(\text{Ca(NO}_3\text{)}_2\) and free zinc (\(\text{Zn}\)).
These examples illustrate the different ways elements and compounds can interact in chemical reactions, either by combining, breaking down, or exchanging components.](https://content.bartleby.com/qna-images/question/4dbd844a-5288-4e1f-bdaf-b70c666aee4d/8b9d015b-26a9-45ad-8eec-511987642359/wty84n8_processed.jpeg)
