To determine the type of reaction expected for the reactant [tex]\( \text{Na}_2\text{CO}_3 \)[/tex] (sodium carbonate), let's analyze the common behavior of this compound when subjected to various conditions.
### Step-by-Step Analysis:
1. Identification of the Reactant:
- The reactant in question is sodium carbonate, [tex]\( \text{Na}_2\text{CO}_3 \)[/tex].
2. Reactions Sodium Carbonate Can Undergo:
- Sodium carbonate is known to undergo specific types of reactions under different conditions. The most common reactions are:
- Decomposition Reaction: When heated, sodium carbonate tends to break down into different products.
- Formation of Complexes or Double Decomposition: However, this usually requires the presence of another reactant.
3. Focusing on Decomposition Reaction:
- When sodium carbonate is subjected to heat, it typically undergoes a decomposition reaction. This is one of the generalized chemical behaviors of many carbonate compounds when heated.
- The general form of a decomposition reaction involving sodium carbonate can be represented as:
[tex]\[
\text{Na}_2\text{CO}_3 \rightarrow \text{Na}_2\text{O} + \text{CO}_2
\][/tex]
- In this reaction, sodium carbonate (solid) decomposes into sodium oxide ([tex]\(\text{Na}_2\text{O}\)[/tex]) and carbon dioxide gas ([tex]\(\text{CO}_2\)[/tex]) when heated.
### Conclusion:
Based on the typical behavior of sodium carbonate under heat, the type of reaction expected for [tex]\( \text{Na}_2\text{CO}_3 \)[/tex] is a Decomposition Reaction.
