Answer

To complete the reaction between sodium nitrite (NaNO₂) and hydrochloric acid (HCl), follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are sodium nitrite (NaNO₂) and hydrochloric acid (HCl).

### Step 2: Write the Chemical Equation
The initial reaction can be represented as:
\[ \text{NaNO}_2 + \text{HCl} \]

### Step 3: Determine the Products
When sodium nitrite reacts with hydrochloric acid, it produces nitrous acid (HNO₂) and sodium chloride (NaCl).

### Step 4: Write the Complete Balanced Reaction
The complete balanced reaction is:
\[ \text{NaNO}_2 + \text{HCl} \rightarrow \text{HNO}_2 + \text{NaCl} \]

### Step 5: Finalize the Reaction
Thus, the final products of the reaction are nitrous acid (HNO₂) and sodium chloride (NaCl).

### Final Reaction
\[ \text{NaNO}_2 + \text{HCl} \rightarrow \text{HNO}_2 + \text{NaCl} \]
