Solution

Solution Steps

Step 1: Identify the Reactants and Their Phases

The reactants in this reaction are barium hydroxide and nitric acid. Both are in aqueous solutions, so their formulas and phases are:

Barium hydroxide: \( \text{Ba(OH)}_2(aq) \)
Nitric acid: \( \text{HNO}_3(aq) \)

Step 2: Determine the Products of the Reaction

When barium hydroxide reacts with nitric acid, a neutralization reaction occurs, producing water and a salt. The salt formed is barium nitrate. The products and their phases are:

Water: \( \text{H}_2\text{O}(l) \)
Barium nitrate: \( \text{Ba(NO}_3\text{)}_2(aq) \)

Step 3: Write the Unbalanced Molecular Equation

The unbalanced molecular equation for the reaction is: \[ \text{Ba(OH)}_2(aq) + \text{HNO}_3(aq) \rightarrow \text{Ba(NO}_3\text{)}_2(aq) + \text{H}_2\text{O}(l) \]

Step 4: Balance the Molecular Equation

To balance the equation, ensure that the number of each type of atom is the same on both sides of the equation. The balanced equation is: \[ \text{Ba(OH)}_2(aq) + 2\text{HNO}_3(aq) \rightarrow \text{Ba(NO}_3\text{)}_2(aq) + 2\text{H}_2\text{O}(l) \]

Final Answer

The balanced molecular equation for the reaction is: \[ \boxed{\text{Ba(OH)}_2(aq) + 2\text{HNO}_3(aq) \rightarrow \text{Ba(NO}_3\text{)}_2(aq) + 2\text{H}_2\text{O}(l)} \]
