Options

A. precipitation reaction
B. double displacement reaction
C. combination reaction
D. (a) and (b) both

Explanation

To determine the type of reaction represented by the equation:

\[ \text{AgNO}_3(aq) + \text{NaCl}(aq) \rightarrow \text{AgCl}(s) + \text{NaNO}_3(aq) \]

we will analyze the components and the process involved step by step.

### Step 1: Identify the Reactants and Products
- The reactants are silver nitrate (\( \text{AgNO}_3 \)) and sodium chloride (\( \text{NaCl} \)), both in aqueous solution.
- The products are silver chloride (\( \text{AgCl} \)), which is a solid precipitate, and sodium nitrate (\( \text{NaNO}_3 \)), which remains in aqueous solution.

**Hint:** Look for the physical states of the reactants and products to understand their behavior in the reaction.

### Step 2: Determine the Type of Reaction
- In this reaction, the silver ion (\( \text{Ag}^+ \)) from silver nitrate exchanges places with the sodium ion (\( \text{Na}^+ \)) from sodium chloride.
- This exchange of ions indicates that it is a double displacement reaction (also known as a double replacement reaction).

**Hint:** Identify if ions are swapping places between the reactants to classify the reaction type.

### Step 3: Identify the Formation of a Precipitate
- During the reaction, silver chloride (\( \text{AgCl} \)) is formed as a solid precipitate. The formation of a solid from two aqueous solutions is a key characteristic of precipitation reactions.

**Hint:** Look for the formation of a solid product when two solutions are mixed, which indicates a precipitation reaction.

### Step 4: Conclude the Reaction Type
- Since the reaction involves the exchange of ions between two compounds and results in the formation of a solid precipitate, it qualifies as both a double displacement reaction and a precipitation reaction.

**Hint:** Consider the definitions of reaction types to confirm your classification.

### Final Answer
The reaction \( \text{AgNO}_3(aq) + \text{NaCl}(aq) \rightarrow \text{AgCl}(s) + \text{NaNO}_3(aq) \) is classified as a **double displacement reaction** and a **precipitation reaction**.
