When ferrous hydroxide reacts with hydrochloric acid, ____ and `H_(2)O` are produced.

Options

A. `FeCl_(3)`
B. `FeCl_(2)`
C. `FeCl_(4)`
D. FeCl

Explanation

To solve the question of what is produced when ferrous hydroxide reacts with hydrochloric acid, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are:
- Ferrous hydroxide (Fe(OH)₂)
- Hydrochloric acid (HCl)

### Step 2: Write the Chemical Equation
When ferrous hydroxide reacts with hydrochloric acid, we can write the unbalanced chemical equation as follows:
\[ \text{Fe(OH)}_2 + \text{HCl} \rightarrow ? + \text{H}_2\text{O} \]

### Step 3: Determine the Products
In this reaction, ferrous hydroxide (a base) will react with hydrochloric acid (an acid) to produce a salt and water. The salt formed from ferrous hydroxide and hydrochloric acid is ferrous chloride (FeCl₂). Therefore, the products of the reaction are:
- Ferrous chloride (FeCl₂)
- Water (H₂O)

### Step 4: Write the Balanced Chemical Equation
Now, we need to balance the equation. The unbalanced equation is:
\[ \text{Fe(OH)}_2 + \text{HCl} \rightarrow \text{FeCl}_2 + \text{H}_2\text{O} \]

To balance it:
1. We have 2 chlorine atoms in FeCl₂, so we need 2 HCl:
\[ \text{Fe(OH)}_2 + 2 \text{HCl} \rightarrow \text{FeCl}_2 + 2 \text{H}_2\text{O} \]

### Step 5: Final Balanced Equation
The final balanced equation for the reaction is:
\[ \text{Fe(OH)}_2 + 2 \text{HCl} \rightarrow \text{FeCl}_2 + 2 \text{H}_2\text{O} \]

### Conclusion
Thus, when ferrous hydroxide reacts with hydrochloric acid, ferrous chloride and water are produced.
